This week, I'm taking a brief break from the usual PCB solution/product technical discussions and focusing on a very interesting capability used with the Cadence Allegro PCB Editor product.You can read all the details from this article - Integrated Optical & Electronic Interconnect PCB Manufacturing in a recent PCB007 update. Most of you know that my primary focus is the "front end" environment for the Cadence PCB products, so when I learn about PCB board intricacies, sometimes it's a bit more than I can comprehend. Nonetheless, there are key takeaways (that actually make sense to even me!) from the article:
As always, feel free to post your thoughts about OPCB technology.Jerry "GenPart" Grzenia
From a schematic perspective, unless you have used the DEHDL (ConceptHDL) Constraint Manager to specify certain constraints, you can always take an existing schematic and use a prior version. So, in your case, you can read an SPB16.3 schematic using the SPB15.5 version of DEHDL. This is NOT the case for the Allegro PCB board files.
Here is problem I'm concerned about is "Will the SPB16.3 be compatible with the lower Version, such as SPB 15.5?That is to say, "How can I open the schematics drawn by SPB 16.3 with SPB 15.5?"
Sure - I"d welcome any PCB designers to provide a more robust technical paper about OPCBs. I'm not a PCB designer and would defer to the experts. In fact, this could make an excellent paper for the CDNLive! 2010 conferences - www.cadence.com/.../default.aspx
Provide some techical paper on OPCB.
