Waiting for available license for Virtuoso(R) Spectre

Hello,

I am going to use "msource" in "rflib" to peform EVM and ACPR simulation.

However, when I run the simulation, the simulation only show the below statement:
"waiting for available license for spectre" and don't proceed

I also try other component in "rflib" but only "msource" have the above problem. I think if there is mismatch in version, other component in "rflib" also don't work

Please advise.

Good days,

Vincent
