[SOLVED] ICC Error - Module 'NOR2X0' is not defined. (MWNL-297)

Hi everyone,

I met an error when I run ICC with the instruction "import_design", shown as following:

icc_shell> import_designs -format verilog -top ChipTop -cel ChipTop_floorplan {./results/compile.v}

Following the the manual of MWNL-297, I checked my netlist file and the FRAM reference library, both of them contain the module 'NOR2X0' .

So how to deal with the problem? I am puzzled.:-x

looking forward to your advice. Thanks a lot!

Hey, were you able to solve the issue?? I'm facing the same problem...

I used -allow_undefined_module as suggested by the error message.
So, its not giving any errors now... but I don't see the FRAM being used in my top level module.

Thanks.

Hi,
I should rephrase the question.... I have created the FRAM and ILM views for the module (to be integrated in the 'top' level).

I don't know how to integrate the FRAM/ILM views while importing the top_level module's verilog file.

Currently, I am including the path of the module_LIB as a reference library - but yet, while reading the module instantiation in the top level netlist, it throws an error {module not found}. This error disappears when I use -allow_undefined_module with read_verilog.


Thanks

Are you giving milkyway reference library(mw_reference_library) properly? I had the same issue which I fixed by giving the right reference library.

Hi surpriya.7,


Thanks for your attention and advice. but the -allow_undefined_module just shade the error from modules that not found.

I solved the problem by giving the right milkyway reference library(mw_reference_library), since the original FRAM format is like AND2X1_1, while the right should be AND2X1:1, when I gave the right one, the proble was fixed.

Thank you!


Cheers,
phuang

Hi dianin,


YOU ARE RIGHT!

I solved the problem today by the same way as what you did, --- give the right milkyway reference library!


Best,
