How to generator a white noise in Pspice? The PWL file is in a
limited time. Is there some circuit that would generate white noise?

I found some disscuss before on google but it's a pity that I can't
find it now. Where should I find the former disscuss?

PWL can be made continuously on-going. Look up "REPEAT"

You could setup an Digital LFSR, and filter the result to give you
band limited white noise.

I have done this some years back.

Does Pspice contains a RND or White function?

"RND", yes, "WHITE", no....

RTFM under notation

Does Pspice contains a RND or White function?

A digital LFSR is a bunch of shift registers with an xor gate in the
feedback.
Its what the computers use to generate a random number.

just hook one up in psice using gates. The output is a maximum length
sequence, which is white.
