Squiggle is an indispensable tool for preparing "viewer friendly"CAD-generated designs and illustrations.
Squiggle enables you to create drawings that are more approachable,allowing your clients to feel more comfortable with your design process.
Squiggle works with all the popular CAD programs, allowing you totransform HPGL and HPGL/2 plot files into hand-drawn art ina matter of minutes. Squiggle allows for the customization of variableline combinations, and allows the user to vary the width and color of up to255 lines with an unlimited number of hand drawn styles to each line.
You can choose from a range of seven preset styles that range from"carefully sketched with a drafting pen" to "scribbled on the back of anapkin."
Each line is drawn independently, and results are not precisely predictable-just like drawing done by the human hand. Styles can be combined into oneimage and pen effects can be can be saved into templates to create custom,"in-house" styles.

May 30, 2002. Kovac Software, a leadingdeveloper of Windows based 2D and 3D graphics software, is pleased toannounce the availability of AutoTRAX EDA, a desktop electronic board-leveldesign software suite for FREE! It is not a demo program and contains notimeouts or limits. It is truly free...
AutoTRAX EDA combines schematic capture, circuit simulation,PCB layout and 3D modeling of both parts and the final board with extensiveCAM integration.
What's the catch? "Well there really isn't one!" Says IlijaKovacevic, founder of Kovac Software. "After our recent successes developing3D software for Template Graphics Software in San Diego and the awardwinning 2D interactive form designer for the e-forms management productmarketed by Cardiff Software, Inc., in Vista, California, we reviewed thecurrent electronics CAD market. While it appears to be flooded withproducts, upon closer examination there is a lot of consolidation at the topend. It reminds me of the story of big fishes eating little fishes etc.Meanwhile at the bottom end there are a lot of 'one man garage products'that are going nowhere. What does this mean for the design communit?, Wellas is usual in industries when the main players such as Mentor Graphics,Cadence and Altium are swallowing up their competitors, prices remain high.For example, just look at Altium's new Protel DXP product which is to bepriced at $7,995US. This is certainly not good news for the designengineering industry."
"The time is now ripe for someone to 'put a cat among thepigeons' and provide a viable alternative. Similar to the way Lunix shook upthe Unix business, the board level EDA industry needs a fresh alternativethat has been designed for the 21st century, not a collection of programseach with a different look and feel bundled together"
Why AutoTRAX EDA? "Here at Kovac Software we have taken afresh look at the desktop EDA market and have coupled our extensiveexperience in user interfaces, 2D/3D graphics and simulation together withthe latest software design methodologies to rapidly develop the next stagein EDA software. Kovac Software is working with leading CAD suppliersSolidworks and Autodesk to integrate the electronic design cycle and themechanical design cycle. No longer can electronic designers 'throw thefinished PCB over the wall' to the mechanical designers saying 'can yousqueeze that in somewhere'".
Schematic Capture and simulation. AutoTRAX EDA features apowerful drag and drop schematic capture module with integral SPICEsimulation and virtual instruments giving the user a virtual electronicsworkbench with oscilloscopes, function generators, spectrum analyzers andmany others. Tight design rules prevent invalid designs such as schematicswith wires going nowhere or connected to blank space.
PCB Designer. The schematic capture module is tightlyintegrated with the PCB designer. The engineer can rapidly create theirfinal boards using the PCB design wizard. The fast interactiveautolayout/autorouter ensures an accurate error free design within a shorttime.
3D solid modeling. In order to ensure that the design willintegrate with the mechanical enclosure, AutoTRAX EDA incorporated theunique Active3D solid modeler to provide views of the final board andcommunicate the design to third party CAD/CAM programs. The Active3D partdesigner is truly a pleasure to work with. The designer can create basicparts, drag and drop pre-made parts from the design gallery and add parts tothe design gallery. Next materials can be dragged from the design libraryand placed onto parts. A built in photorealistic renderer provides aprofessional photographic quality image for incorporation into otherdocuments.
CAM collaboration. Finally the designer can send theirfinished work to production using AutoTRAX EDA's comprehensive CAMinterfaces. Kovac Software is working closely with SolidWorks and Autodeskto provide a complete desktop design solution.
Open database. All the modules are tied together viaAutoTRAX EDA's distributed open format part database.
"The desktop EDA industry is about to get a wake-up call!"says Ilija Kovacevic with a wry smile.
AutoTRAX EDA is available for free download fromthe site complete with printable Adobe PDF manuals. Inaddition printed copies of the manual can be ordered on-line.

Recently Kovac Software developed the award winning formdesigner for Cardiff Software in southern California, see
About Ilija Kovacevic:
Ilija Kovacevic received his B.Sc.(Hons) in physics atBirmingham University. After working in the electronic industry at bothNational Semiconductor and Motorola, he founded Kovac Software. His mainresearch interests are in computer simulation and making complicatedsoftware seem simple. In his spare time he combines cycling with competitivepower lifting.

Subject: Re: pcb router

There are many pcb routing tools. If they are good or bad for your work is difficult to say. It depends on what you need to route (single, dual, or multilayer; size; smt/through hole; emc; groundplanes; forward/backward annotation, design rules check etc.). And it depends on how much money you want to spend. And it also matters if it has to be a windows program, unix, dos or other environments. We are happy with our PCAD MD8.6 but others may have different opinions. PCAD MD8.6 with a shapetech router is not too bad but it will be expensive.

The famous chipdirectory has a page with some pcb routing tools. Look on the homepage for Manufacturers and follow the link to CAD programs.

The Institute for Interconnecting and Packaging Electronic Circuits (IPC) is a trade association representing over 2200 companies in the electronic interconnection industry worldwide. If you follow the design link from their homepage you will find info about email forums about pcb layout, links to many suppliers of layout software and more. On their email forum (they have also an archive on the web) you can get lots of info.

Try Protel.
We use their systems for schematic capture and PCB layout. Not the least expensive, but professional quality, good support. From what I can gather from conversations on this group and others, the really low cost systems ($500- $1000 USD) don't work too well....

I use the PADS PowerPCB with the autospectra router and Viewlogic's Viewdraw for schematic capture.

I have also used Orcad's capture and layout programs and found them to be non intuitive. It seems you have to do everything backwards to what you would expect.

Orcad is pretty much has a set price for their packages where with PADS you can get what you need.

I like the PADS best!!!

Several people have mentioned their favourite CAD packages here already. The Specctra router is the tool you really want for autorouting. IMHO, products like PADS, Protel, Ultiboard, or whatever, are merely a means to create the parts and get the design into Specctra. I have used all of those products over the years and each have their good and not so good points. I don't think it is reasonable to say that X is better than Y. Only that I am more familiar with X or that X is missing a feature that I used a lot with Y. I've tried many of the autorouters that have been offered, too. Again, some perform quite well under particular circumstances, but no board designer really expects to have all the work done for them.

The Specctra though, really is in a league of its own. You can throw a board at it,straight out of the box and it will both succeed and do a reasonable job. You then have the ability to control it by putting rules on to nets, regions, components, layers, etc. The rules are in the form of a programming language and that gives you the ability to tell the router what you can see and it can't. You can have the rules change as the routing progresses. The flexibility is excellent. This software was obviously written by people who have done a lot of PCB design themselves. It really shows.

Not suprisingly, it isn't cheap. If that doesn't deter you, they have an auto-placement that actually works too. Then there is DFM, semi-manual routing, route rules based on crosstalk, impedance, etc. The list goes on (well beyond my budget).

I'm not associated with them in any way, other than being a very satisfied user.

Kerry Berland:

Try Protel.
We use their systems for schematic capture and PCB layout.

I also use the Protel schematic and PCB system. It's o.k., but the autorouter is not very good, I think.

Paul Humphreys:

We use POWERPCB from PADS with the Spectra Autorouter and always are able to 100% complete the design.

That's right, the Specctra-Router is really great. It's possible to export the PCB from Protel to Specctra, and the result is always good!

I use Circuit Maker which has Trax Maker incorporated into it (MicroCode Engineering). I believe it is probably about the best for under $600. I would not recommend it to someone working all day but for someone such as myself where I may cut a PCB about every week or so it is just right.

They supply a demo at on their site (Sorry I don't have a URL handy).

I have found the autorouter module in the Eagle PCB package by CadSoft to do a surprisingly good job for a low-cost PCB CAD tool.

Try or

The whole package (schematic capture, board editor, autorouter) goes for about US$1200.00 and does amazingly good work for the price.
