Thanks Ed. The property NODRC_SYM_SAME_PIN was actually a PCR that I submitted. It will drastically reduce constraint areas on fine pitch components thereby boosting performance.

DRC Suppression in 15.2 (June 28, 2004) 3 new properties are available to suppress typical 'false' type DRCs. In 15.0, the property NODRC_SYM_SAME_PIN was introduced that suppresses pin to pin spacing errors within the same component. Use of some of these properties may alleviate the requirement for constraint areas or time spent reviewing each instance of error. * NODRC_COMPONENT_BOARD_OVERLAP - apply directly to component placebound shape when components overlap the package keepin area. Typically these components tend to be mechanically constrained like connectors, switches and LEDs. * NODRC_ETCH_OUTSIDE_KEEPIN - apply directly to etch elements outside the route keepin area. * NODRC_VIAS_OUTSIDE_KEEPIN - apply directly to vias placed outside the route keepin area. These vias tend to be GND stitching vias in large quantities. The use of temp groups is recommended when suppressing a large quantity of vias. -----Original Message----- From: Musetti, Carl [mailto:cmusetti@xxxxxxxxxxxxxxxx] Sent: Thursday, June 24, 2004 9:00 AM To: icu-pcb-forum@xxxxxxxxxxxxx Subject: [PCB_FORUM] Re: ICU2004 - PCB Top 5 Issue's I completely agree with you Jerry Allegro DRC system is one of the strongest features of the tool and to have it made so that errors are acceptable is unacceptable! -----Original Message----- From: Schwartz, Jerome [mailto:jschwa01@xxxxxxxxxx] Sent: Thursday, June 24, 2004 7:48 AM To: 'icu-pcb-forum@xxxxxxxxxxxxx' Subject: [PCB_FORUM] Re: ICU2004 - PCB Top 5 Issue's For all of you that have been doing real design work for 25 years or more please, please, please, do not let something like this pass through to Cadence. An error is an error. There is no such thing as a false DRC. The system is trying to tell you that something is wrong. Understand the error, make it your friend, then correct it. It will go away, no hard feelings. I have never sent a design to be fabricated with DRC's. There's always a way to correct the error. I've seen most of it, if not all. No DRC at required areas: False DRC errors should have some way of making the tool not report them as errors. Regards, Radha Krishnan G.

Now is your chance to influence the functionality of the Cadence PCB products. This year we are doing things a little differently than previous years by having individual Top Five issue lists for the following Allegro Platform products: Concept HDL, Capture/CIS, Allegro, APD, SpecctraQuest/SigXP/CM and Specctra. The schedule will be as follows: Input Begins: June 22, 2004 Input Ends: July 19, 2004 Top-5 Voting Begins: July 26, 2004 Voting Ends: August 6, 2004 Results Published: TBD Cadence's response to the Top-5 Issues will be shown as a presentation at the 2004 International Cadence Usergroup Conference and shortly there after the responses will be posted at <http://www.cadenceusers.org/> http://www.cadenceusers.org. Only the responses, and not the entire presentation will be posted. Please visit the following link to submit issues for this years Top 5 voting. http://www.cadenceusers.org/sigs/pcb/pcbIssuesSubmit2004.html In addition please checkout our website for Conference Updates, Schedule and Registration Specials We are looking forward to hear from you ICU PCB SIG
