Hi, I am university student currently learning Cadence tools. I use DIVA for DRC, Extract and LVS. Process : TSMC18RF (0.18um) I am currently doing layout of an 10 phase oscillator circuit. When I run DRC on my completed layout I get no errors. When I run Extract with the "Join nets with same name" switch ON and Parasitic RC Switch SET. I get the following errors: Figure Causing Multiple Stamped Connections Figure Having Multiple Stamped Connections if i set the Parasitic RC switch OFF - that is if dont set any switches ( no parasitic extract ) I DONT get these errors or ANY errors. My Design also passes the LVS succesfully my design has following layout structure: VDD Rail ==================== BUFFER Amplifiers ==================== GND Rail ==================== Differential Amplifiers ==================== VDD Rail ==================== Buffer Amplifiers ==================== GND Rail ==================== I googled these error messages and I found some explanations but I dont seem to violate any that is mentioned in these expalnations. Like I have connected the GND and VDD properly. the divaEXT doesnt like me putting 2 separate ground Contacts. my Ground contacts are M1_SUB. if put them at separate places i get this error. How do I go about resolving this issue? please help.
Typically the problem is that you cannot check for substrate connection when doing parasitic resistance extraction. You can not do this because the metal1 layer gets broken up into resistors (parasitic) so every metal1/ptie and metal1/ntie contact is on different net. Basically what you have are two well contacts that have different nodal information. Try changing the rule (geomStamp) in your divaEXT.rul file so it does not use the "error" keyword when parasitic resistance is in use.
Another place to look is the p2lvs file. In this file you define (in the first line) which are your substrates and how are they "stamped" together. Personaly, I had many problems understanding all the options there till the end, but playing around with it might help.Ezra
