Hi, folks:
I've got a question on Simulation DCO's. The DCO itself is out of the question.
the problem is how to simulate a block (i.e. DCO) for linearity?
for example suppose the the DCO have 6 input control bit, each code(e.g 010101) will generate sinusoid output at specific freq.
to test linearity I should test all the codes, now the problem is how to test all the code and freq. that is generated?
because I should RUN Hspice \[{2 }^{6 }\] times, to test \[{2 }^{6 }\] states !!!
and i think it is impassible:thinker:
(I know about ".alter" and I think it's not good chose here)
Please suggest, thanks.
