forward-annotation saif

The manual said for gate-level, producing forward-annotation SAIF just follow 2 steps:

1.read_lib(ASCII format)
2.lib2saif

1) I am confused. Doesn't it need read in gate-level netlist? If don't need, how does DC know what or which information it should write to saif file, but not all information in library?

2) When I use read_lib, DC told me a lexical error (a syntax error) found before lib or phys_lib. What does it mean? Why does it occur? And how can I solve it?

Thanks a lot!
 

lib2saif

1. the library contains the SDPD information

2. You need to use the lib2saif command on the actual Synopsys database format (.db) file that has the library in it. For example, read -format db libary.db
lib2saif core_fast.db -output ssc_core_fast.saif
