Proper analysis about IMD(SMPTE) Simulation

mjlee

Hi.

I trying to check IMD(SMPTE) performance of my design stuff.

Test inputs are 60Hz, 7kHz

Sampling clock:12.5MHz

Block : Sigma Delta DAC

But It is expected to take a long time to verify the simulation results if I use transient analysis.

1/60Hz=16.7ms < 262144*(1/12.5M)=21ms

What is the efficient analysis method?

Thanks

MJ
