HSPICE postlayout simulation out-of-memory error

[hfr002]

Hi,

I am working on a Mixer and LNA postlayout simulation. The layout includes the bonding pads and some decoupling capacitors. The total area is 1sqmm approx. I am using Hspice RF for the simulation and the commands HB to obtain the P1dB, IIP3, and NF.

Hspice will run until the following message:

hb residual = 5.656854e-001
Error: Out of memory (used = 0.0 Mbytes, requested = 65.6608 Mbytes).


I have increased the virtual memory of Windows Xp usings Xp's own virtual memory administration tool, but it seems that Hspice does not recognice the newly allocated memory.

Does somebody know a procedure to increase the memory allocated to Hspice?

Thanks
Hugo

you should try to use 64 bit executables of hspicerf
