Hello everyone. Please bear with me until this becomes relevant to signal integrity ;) I've written an open source PCB design software called PCBmodE http://bitbucket.org/boldport/pcbmode http://boldport.com/pcbmode that allows me to design in any shape onto my circuits, on any layer. It's at a very early stage of development, but I've been designing boards with it for the past year. You can see examples of my work here: http://boldport.com http://boldport.blogspot.com http://boldport.tictail.com http://boldport.blogspot.co.uk/2013/09/the-lifegame.html http://boldport.blogspot.co.uk/2014/02/so-you-want-to-manufacture-your-printed.html http://boldport.blogspot.co.uk/2013/11/an-engineers-emergency-kit-business-card.html I'm generally looking for applications where 'form contributes to function', and I think that there is a pretty clear case for this applying to the signal integrity of high speed digital and analogue design. I'm exploring the potential of this application space in order to evaluate whether this is an avenue to concentrate on for PCBmodE development and/or design work. I ask for your feedback. Some initial questions: 1. Does the need ever arise for creating traces that are not easily supported by your EDA suite? 2. Do you ever use third party tools for designing in unconventional (but functional) shapes into your designs? (Is that process working well?) 3. Is there compelling evidence that the capability to design in arbitrary shapes contribute to better signal integrity in a significant way? Any thoughts would be greatly appreciated and helpful! A bit about me: I'm an electrical/computer engineer. I've done a lot of FPGA work, circuit design, and was an academic for a while during a PhD at Cambridge where I looked into security of hardware devices. Only recently have I started embracing my artistic side ;) https://www.linkedin.com/in/saardrimer Many thanks for your kind attention. cheers, saar. ------------------------------------------------------------------ To unsubscribe from si-list: si-list-request@xxxxxxxxxxxxx with 'unsubscribe' in the Subject field or to administer your membership from a web page, go to: //www.freelists.org/webpage/si-list For help: si-list-request@xxxxxxxxxxxxx with 'help' in the Subject field List forum is accessible at: http://tech.groups.yahoo.com/group/si-list List archives are viewable at: //www.freelists.org/archives/si-list Old (prior to June 6, 2001) list archives are viewable at: http://www.qsl.net/wb6tpu
