Same net DRC off. How could we avoid that via on pin problem. Or how could we identify the DRC.
Under your Physical Rules, ""Set DRC modes..."" button, make sure ""Pad/Pad direct connect"" is set to ""Always"". Then under Physical Rules, ""Set values..."" button, make sure your ""Pad/pad direct connect"" is set to ""Not Allowed"". This will flag a DRC when the via is within the SMT padstack. If you have same net checking turned on, your via - pin spacing constraint will apply. You may want to look at SourceLink solution 11165996 for more info. I hope this helps.
No Its not Applicable to my query. I have set the, Same Net DRC ""off"". If I route with a via on a SMT pin , it should show DRC. How can I achevie this.
Just to make sure... Please verify: 1) Under your Physical Rules, ""Set DRC modes..."" button, you have ""Pad/Pad direct connect"" set to ""Always"" for the 'proper' constraint set? 2) Under Physical Rules, ""Set values..."" button, you have ""Pad/pad direct connect"" set to ""Not Allowed"" for the 'proper' constraint set? If so, it would probably be best to open a Service Request with Cadence Support to look at your design.
Thanks I will get support from Cadence
I have a similar issue. I have added my via so it is just about tangent to the smt pad. It actually overlaps the smt pad by a bit. Is there a way to have allegro not drc?
If you are using 15.5.1 latest ISR, try going to Keyboard Commands and look for a command called "via_checks_report" and see if this will help identify your issues.
