I have a problem when I do a LVS check using calibre. Aparently it shows LVS clean my layout for a older version of calibre, but when I update for a latest version there seems to some errors in LVS.
Could anyone tell me how is that errors do not exist for older versions of calibre and it shows errosthe latest ones? Do I have to change some settings ?
LVS errors may depends upon many things (based on your comment)
1. Due to schematic changes
2. Any Rules updates in Rule files
3. In new version layout is change from previous version
Please let us know what kind of LVS errors you are getting? This will helps in seeing the problems.
Its not your fault dear. Just do one thing. Try to explore the files which you are including for LVS, i mean tech files for a particular node. Every foundry will give the Calibre version with which it is compatible with, Like "EDA TOOL VERSION: Calibre 2007.3_36.25" . So use the recommended version and leave the rest to the EDA vendors.
