Run Monte Carlo with ADE Explorer

lxc123

I got this error when running Monte Carlo with ADE Explorer:

"ADE Explorer Message 9512

ERROR(EXPLORER-8512): Cannot run simulation because the Xserver Virtual Frame Buffer (Xvfb) executable is not found in your Linux installation. Install Xvfb at /usr/bin and then run simulation."

The schematic is a simple inverter. I had followed the user guide but didn't know why. And it was okay when running without Monte Carlo. Here is my setting:

(because cannot upload pictures, just text)

1. simulator spectre;

2. analyses: tran 0 5n;

3. Corners: mc

Temperautre 130

Design Variables: VDD 1

Model Files: just the same as without Monte Carlo, and chose mos_mc this time；

4. run a fixed number of points: 2

variation: all

method: standard Monte Carlo

chose "save waveforms" and "save statistical parameter data"

sampling method: low-discrepancy 

seed: 12345

first point: 1

5. chose corner-mc, chose Monte Carlo Sampling, chose plot "vin" and "vout", and then click on "run" button. 

Opps, ERROR！

is that anything problems with my setting? or How to fix this error?

    The error spells it out pretty clearly. You need to install Xvfb! See The New Virtuoso nograph Server Xvfb was made default

    Will it cause this error if get the warning "Failed to check out license ADE XL" and then turn to ADE Explorer, or there are some problems with the setting? It's just so strange that I can run it successfully with ADE XL before I go to ADE Explorer. If just need to install Xvfb, I will try to ask the administrator for help!  Thank you so much!
