Summary
Simulations can be run in Tanner T-Spice and saved in Nutmeg format so that the results can be displayed in other applications such as EZ-Wave. This allows for simulations to be generated using a T-Spice license, and calculations and viewing can occur on an AMSV license.
Details
Since AMSV v2020.3, EZ-Wave started supporting nutmeg binary output files generated by T-Spice. This enables T-Spice simulations to be opened in EZ-Wave.
To set the filetype in T-Spice to nutmeg binary format, the setting can be added in S-Edit simulation settings or by directly amending the netlist file. I have explained both methods below.
Via S-Edit:
- Open Setup > Simulation and change to the additional commands tab.
- Under Additional SPICE Commands, add the following line:
.OPTIONS filetype = rawbinary
- The simulation folder can be defined under the General tab and listed next to Simulation Results Folder
Via Netlist:
- Add the following command to the netlist file:
.OPTIONS filetype = rawbinary
- By default, the filetype command is set to tsimdb which is the format for Tanner Waveform Viewer
In EZ-Wave, open the <simulation_name>.raw file stored in the simulation results folder. This file contains the simulation results in nutmeg binary format.
