Hello everyone,
I am trying to write a 2x1 multiplexer using the mems switch in veriloga. But when i try to simulate the circuit i am getting errors.
ERROR (SPECTRE-11005): Matrix is singular (detected at `out').
ERROR (SPECTRE-16080): No DC solution found (no convergence).
Here is my code.
Please help me. I am stuck at this point.
Thank you
