I am tring to run LVS in ASSURA. It is failing & error file says :
"*WARNING Corrupted type field (0x0x4f35d) at 0x0x4880cf8 in file <file location>layout.cdb
*WARNING bad type table pointer 0x0x2a91d0004f35d at 0x0x4880cf8 "
Please help. I have no clue how to solve it.
Hi AritraWould you please retry using latest version of Assura? If it still gives the same error, please file a service request to your local Cadence support. Thanks.Best regardsQuek
In reply to Quek:
I have another error while running Assura LVS. After finilizing comparing layout and schematic it fails due to a (possibly some sort of DRC) error:
(66) ###### Eight levels of metal M1-M2-M3-MQ ...
I cannot see any reason because I am using an 8-metal process and using the correct metal layers. Although I can still reach the LVS result from the files generated, the real problem is due to extraction. Since LVS fails I cannot do the extraction either. Any idea about this issue?
Below is the end of the log file:

In reply to Sevil Zeynep Lulec:
The problem might be something to do with how the LVS rules are written, or it might be an issue with the specific version of Assura. You didn't mention which technology or Assura version you're using, but that said, I couldn't find any reports of this failure mechanism. Note, the error is almost certainly due to the ilGetInt bit, not the ##### Eight levels ... part (which is just a comment, I think).
Almost certainly the best thing you could do is to contact customer support - I think we'll need to see the data. I'd check that you're using recent versions of Assura and have checked with the foundry if you have up to date rule decks or if they've seen the same problem.
