When removing all extra '}' of SIMPLE .lib, other issues occur.
(2) Missing timing arc
This issue happens for six libraries: SIMPLE(RVT, SLVT)(FF, SS, TT).
The error message is as below:
Cell ‘’, pin ‘Y’, There is a missing timing arc between pins ‘’ and ‘Y’ in the ‘’ cell. (LBDB-23)
Specifically, NOR3xp33, NOR4x3f, NOR4xp25, NOR5xp2 cells have this error for all input pins.
(3) ccsn_template issue
This issue happens for SIMPLE_RVT_FF only.
The error message is as below:
Cell ‘’, pin ‘Y’, The ‘css_template’ refers to a nonexistent or empty ‘lu_table_template’. (LBDB-259)
There are hundreds of errors relating ccs, but the error is nonexistent or empty template.
(4) name mismatch and extra library for SIMPLE_RVT_SS
asap7sc6t_SIMPLE_RVT_SS_nldm_211010.lib.gz has library named "asap7sc6t_SIMPLE_RVT_SS_nldm_210917" (line 34) and "asap7sc6t_NAND5xp2R_RVT_SS_nldm_211010" (line 53410).
I guess 210917 should be changed to 211010.
Also, I cannot find any reason why there is an extra library in the same file for NAND5xp2R.
Please check all issues and would be appreciated if those are fixed.
There are four issues for converting lib to db using libcompiler (checked with both 2022.12 and 2018.06 version). Note that all libraries are NLDM.
