Creating LM view for reference library

[harshendu]

specify location of lm library

Hi,
I am a new user to Astro. I have been attempting to do the P&R for a particular netlist, but i am encountering an error while doing the CTS

The warning that is issued to me is "No timing information in any libraries".

I checked my refernece library, provided by the vendor. It contains only the FRAM view and no LM view. I tried to create the LM view using the .db library files along with this library, be i have been unsucessful in this attempt.

I'm not even sure if i am on the right track! May i know if i have understood the problem correctly and how should i go about solving this?

Thnaks

lm view

Thanks a lot Shankar, now i have the LM view and the FRAM view for my reference library... Is this sufficient for building my design Library or do i still need to add anything else into my reference library??

Hey neihar,
The following is from my command log file generated when i created the LM view to my reference library. Just change the paths and names of the corresponding files(they have been marked in bold for you), and execute the commands.

gePrepLibs
setFormField "Library Preparation" "Library Name" ""
formButton "Library Preparation" "browse..."
setFormField "Library Preparation" "Library Name" "ref_lib"
formButton "Library Preparation" "importLMDB"
formButton "Library Preparation" "selectDB"
setFormField "Library Preparation" "Min DB To Import" "/home/library/fsc0l_d_sc_bc.db"
setFormField "Library Preparation" "Max DB To Import" "/home/library/fsc0l_d_sc_wc.db"
setFormField "Library Preparation" "Typical DB To Import" "/home/library/fsc0l_d_sc_tc.db"
formOK "Library Preparation"


Hope it works for you..!
