Rookie question: Does ngspice+xspice support direct VCD import in a similar manner to ADE/hspice/spectre? I have VCD data used by a FSM to control an analog block, and have been searching for a way to apply the waveforms to the block with ngspice39. I saw methods/scripts online about converting the VCD to filesource format and importing the waveforms. However those scripts have failed to parse my VCD file (this file has successfully worked with ADE in the past). Figured I should ask before making my own VCD -> filesource script.
