Insufficient memory in PNOISE simulation

 Hi Andrew,

I'm Using Cadence 6.1.5 and MMSIM 10.11. I have enabled 64bits.

I'm trying to do phase noise analysis with PSS HB and PNOISE for post layout extracted netlist. I got the following error:

 
Mem Used: 12813.8 MB (Memory Exhausted)
Fatal error found by spectre at freq = 10 MHz during PNoise analysis `pnoise'.
    FATAL (CMI-2002): Insufficient memory available. To reduce memory, please refer to "spectre -h memory".

However, I have near 45GB free memory! Why PNOISE cannot use all the available memory? How can I reduce required memory?

Here is my Circuit inventory:
