failed to get a shared lock on library

Hi,

Anyone using NCVhdl?
The Cadence tool which i'am using is showing some errors when written testbench & compiled? but if it is written in verilog it does not show any error. Can anyone using NCVhdl can guide me.

I've used it in the past. Unless you show the exact error message and some piece of code, it is next to impossible to help. There are several differences bet'n Verilog & VHDL and hence I can't help without seeing your code/error.

So - post the error/code for help

Error: Failed to get a shared lock on library 'ambit' (No locks available)
Error: Failed to get a shared lock on library 'cds_assertions' (No locks available)
Error: Failed to get a shared lock on library 'ieee' (No locks available)

Usually this means that the contents of that library is stale/invalid. I've seen this happenning if my NC run crashed previously. In your case you seem to have problems with pre-compiled libraries - are you sure you are using same versions of NC? i.e. is the version used to compile "ieee" same as the one you are trying to use right now?

Other options are:

1. try and compile ieee, ambit etc. yourself to local libraries.
2. Contact support @ CDN.

Good Luck
