Hello,
When modelizing fully differential OTA I've met strange error from veriloga parser.
Here are 2 variables that modelize output small-signal behavior
Code: V1P_AC = Gain_AC * laplace_nd(vin_dif, zeros, poles);
V1N_AC = Gain_AC * laplace_nd(-vin_dif, zeros, poles);
and here is common mode processing
Code:V1_CM = Gain_CM * laplace_nd(V(Vbpfb), zeros, poles);
Then I add common-mode part with small signal part to form outputs:
Code: V1P = V1P_AC + V1_CM;
V1N = V1N_AC + V1_CM;
When I compile this code, following error appears:
Error: dynamic quantities must be directly accessible to the outputs.What does this error mean?
Regards
Pavel.
