| In this directory contains an example for generating a spice output using two | |
| different spice modes, normal analog transient simulation and event-driven | |
| digital simulation as supported by ngspice xspice sub-module. | |
| Each test bench can be run separately by either running: | |
| - testbench.sh, to start analog simulation or | |
| - testbench_digital.sh for mixed-signal digital simulation. | |
| The later case also includes pure verilog simulation using the iverilog | |
| and gtkwave for comparison. | |
