I just installed the HyperLynx v9.0 and opened a demo design and exported a 3D via into HyperLynx 3D EM. However, the "Simulate" under menu "Process" is greyed out, so I can not simualte this 3D via model. What is this problem? Does the HyperLynx 3D EM require extra license?
Linesim GHz license support 3D via extraction with Hyperlynx environment. If you wanna invoke standalone Mgrid applicaiton to run via solver you have to have Hyperlynx 3D EM license. I guess you may have only Hyperlynx 3D EM designer license.
