ERROR (ADE-3023)

Hello to everybody,

Recently I have begun working with Cadence Virtuoso 6.17. When I want to perform an ADE-L simulation I obtain the following error in the CIW:

ERROR (ADE-3023): Cannot run simulations because the spectre executable is not found in the specified 'UNIX $PATH' setting.
Perform the following steps to specify the simulator executable path:
1.Download and install the required tool version from http://downloads.cadence.com:
- For analog simulations, download and install MMSIM
- For AMS simulations, download and install INCISIVE
2.After the installation is complete, set the tool installation path in your $PATH as below:
set path= $<MMSIM_INSTALLATION_PATH>/bin/:$<INCISIVE_INSTALLATION_PATH>/tools/bin:
$<IC_INSTALLATION_PATH>/tools/bin:$path

I have several doubts related to this error:

1) How can I check out where MMSIM and INCISIVE are installed?

2) Where do I have to write this thing of "set path=$<MMSIM..."?

I've searching on Internet about how to solve this issue. People say that there's a file ".cshrc" where the variables are defined, but instead I have found a ".profile" where the license is defined... I don't find any example of typical file ".cshrc" or ".profile".

I would appreciate so so much an answer that could help me to solve this error and begin to simulate circuits. I apologize because I have no idea about unix, and unix variables.

Thank you so much,

Irene
