LVS not running

Hi Sarvani

It is quite strange that schematic mfactor has been turned into a string. I think you can resolve the first problem as follows:

=== original ===
schM = schPlist->m

=== New ===
schM = schPlist->m
when( stringp(schM) schM=atof(schM))

For the 2nd problem, please use enable "Additional functions" on Assura LVS form and use "joinableNets" function. Please refer to Assura command reference for more details.

Best regards

 Hi Quek,

             I am very greatful to you. I followed your suggitions. Its working good and sorry for delay replay.

Thank you,

sarvani.

Hi Sarvani

It looks like this is an extraction problem and not a comparison problem. Your layout resistors cannot be extracted. I think you will need to re-check your extraction rule for the resistors.

 Hi Quek,

              Is there any set up is required for hirerchy LVS checkup. When I am running LVS for top level cellview then Net and Devices errors are occured. In nets report it is showing that less no. of nets in schematic than layout. For example I have VDD in Schematic and layout then in LVS error report it showing that schematic has 1 net for VDD ( I mean VDD(1)) but 8 nets(mean VDD(8)) in layout. For more information please reder to the LVS error report. Please let me know if any set up is needed. Please ignore parameter errors.

Hi Sarvani

No special setup is needed for Assura hierarchical LVS. From the cls file, it looks like the net mismatches might be due to the inability to combine parallel spcnmos and spcpmos devices. Perhaps you can check the compare rules file to see if appropriate mergeParallel cmds are present for these devices.

By the way, actually it is really better for you to upload the cls file as an attachment and not cut and paste into the forum post because it makes the post very long and hides your question among the other info. This discourages other forum users from reading the post and helping you.  : )

Hi Sarvani

One more point, this question should be posted to the CIC forum and not this SKILL forum. : )
