I am using The addaccu tutorial.htm- should I be using something different? Perhaps the addaccu.tgz is newest? but the pdf in that seems to have paths different again- /cad. To get $7 of the tutorial to work, in addition to the changes mentioned in my previous post, I changed the lib environment line from sclib to: setenv MBK_CATA_LIB $TOP/share/cells/sxlib:$TOP/share/cells/sc2sxlib $8. Here I have inserted /share into the path for cmos_7.rds, and the paths for the sclib and padlib. The result of lynx is a missing value in line 234 of cmos_7.rds, which is NTRANS NTRANS C_X_N RDS_POLY RDS_NDIF RDS_NDIF Havent got a way round this (though have yet to try replacing the sclib with sxlib:sc2sxlib as per $7 fix).
