> You have to use cmos_8.rds technological file (not cmos_7.rds). > The file name of the RDS technological file is set with the > RDS_TECHNO_NAME environment variable. $7. I am finding 29 cells 41 nets when running $7 Core Layout Generation, against the tutorial.htm 25 cells 37 nets. Although the auto place and route seems to work, there is a warning message that the logifchain is missing on logif core. $8. lynx, with cmos_8.rds works. $8.2. lvx, has 16,29,166 versus tutorial ..250. And mbk warning logifchain is missing on logif core. simulation of the extracted core asimut core core result fails to complete. Is this all due to the $7 missing logifchain problem, can you suggest a fix? Thanks Regards Chris
