I got the following error on plotting results when doing ac analysis with my layout.
*Error* Trying to plot expression <VF("/I30/60:net1378" "/home/heyongsheng/simulation/test_delay_line/spectre/config") >, which do not evaluate to be plotted.
Chances are little that this problem stems from the net expression "/I30/60:net1378" because I chose this net from the layout and I managed to get the same net expression plotted when doing tran analysis. I guess the error is caused because the psf file is larger than 2G. To confirm it, I reduced the sweep points per decade from 1000 to 100 when doing ac analysis. This time, as the psf file is no longer larger than 2G, the net expression was plotted successfully without the above error. Does anyone know the exact reason for this problem? How can I solve it? I appreciate it for your help.
P.S. The sub-version of my icfb.exe is 22.214.171.1240.6.151 (32-bit addresses). The version of my spectre is 126.96.36.199 32bit. My waveformtool is wavescan.
