[SI-LIST] hspice issue

Hi, all:function SetDomain(d) { document.domain = d; }

Did hspice included the variation of gm (CMOS) over broad frequency upto 20G ?

Since it takes electrons finite time to pass through the channel,  so there 
will be a up-limit frequency which eletron will forever stay in the channel.

Did hspice take that into account? In another way, if no parasitic capacitance 
exists, will the cut-off frequency of mosfet in hspice simulation be infinite ?

(The reason I did not do the test it myself is that it looks that impossible to 
remove all cap in the process file, maybe some avanti guies can answer this 
problem.)
