how to resolve multiple worklib in NC sim?

[kel8157]

We are receiving multiple IPs from vendor, which both use ncvhdl with default worklib. On integration side we are advised not to change the compilation scripts due to complexity.

How do I resolve these during system integration? There will be multiple path for worklib after including each othe cds.lib. NCSIM will take the later definition of the cds.lib and discard the former thus one IP went missing after elaboration.

two way to solve this problem:
1. modify the lib name
2. compile different lib first, then compile top to add option for selected lib

How do I modify the libname w/o changing the compilation script provided by IP provider? Each IP is of million gates and no option is given to change libname.. and communication with IP2 provider (the simpler IP) is not going too well..

Each will instantiate their module like this in cds.lib

define worklib ${IP1_path}/compile/run/worklib

define worklib ${IP2_path}/compile/run/worklib

Then in configuration of each IP's testbench..

For all: IP1 USE CONFIGURATION worklib.ip1_config;

For all: IP2 USE CONFIGURATION worklib.ip2_config;

Thus at the integration, I include both cds.lib and only IP2 remains..


Can you explain the "add option for selected lib"? I tried this in cds.lib

define worklib1 ${IP1_path}/compile/run/worklib
define worklib2 ${IP2_path}/compile/run/worklib

but ncelab doesnt like this..
