Matlab filtered PRBS inport in Cadence.

Hi Team,

I have created a signal in Matlab, which is a Pseudo-Random Binary Sequence (PRBS), Then I FFT the sequence and filter the result in the frequency domain and then reverse FFT to form a time-domain sequence signal. (At this time, the sequence is no longer binary.) The output looks like following sequence.

-1.15818813666193
-1.70492924565975
-1.62941012941305
-1.64014136911552
-1.65101800539937
.

.

-1.29500595699341
-0.978643692505799
0.208647204966326
-0.732686481259916
-0.783245689345706
0.809376092317872
0.684607565009403

I am trying to import this resulting sequence into Cadence schematic as an input signal to my analog receiver, which I designed in Cadence virtuoso.

Can anyone teach me how to do that?

Thanks

What is the problem you are trying to solve ?

There is a prbs source in Cadence, why don't you want to use it instead ?

Riad.

Hi! Thanks for your reply. I see what you mean. But unfortunately, I have to do the pre data processing in Matlab. Can you please let me know how to import an array of numbers (as shown above) as a voltage source in Cadence.

Use a pwl source with "Waveform Entry Method: File" (see https://support.cadence.com/apex/techpubDocViewerPage?path=spectreRFinExplorer/spectreRFinExplorer19.1/Chap8.html#pgfId-1065518).
