RTL Compiler code clarification

[Arvindh19]

Hi ppl,

When I wrote a tcl script to source into rc compiler, I included the following

write_design -encounter

which created a series of files to be used with encounter.

One of them is a .g file. When I compared the difference in the file content between .g file and the file obtained by using the write_script command, I found that few extra lines were present in the .g file. What exactly is this .g file? and where is it used?

and... what is the use of the setup.tcl file generated by the same command? I know it reloads the RTL session but how?

Regards
Arvindh.S

Just a suggestion - you should look into the documentation as well for detailed understanding. Its all there.

ideally both the " .g " should be same - you should check which these differences are and why.
RC has its own set of constraits as well - which are exported by the write_script command, not only constraints but ideally it captures the entire design environment and re-populates it when you source the setup.tcl back
