By virtual TPM you mean the implementation on modern Intel and Ryzen platforms in the cpu correct?

No, I mean a swtpm running in a hypervisor and presented to a VM as a discrete TPM.

I would not assume so as these are firmware implementations and as such would not use the simulator directly

edit: also look at the link you can see clearly that Intel is not effected but AMD is unknown...
