默认 RTH=-1;CTH=-1;
看到文件描述涉及芯片内die的数量引起的换算问题;请问哪位熟悉这组参数? ************************************************** aLdefine FSL_MET_MODEL_sparm_s4p (n1 n2 n3 n4)
parameters File="test" RTH=-1 TSNK=-1 CTH=-1 \
Sparm_File="test.s4p"
Number_of_Die=1 ;
; options block for easier DC convergence
Options:Options_MRF1 Temp=25 TopologyCheck=no
ForceS_Params=no MaxSpectralSize=512
V_RelTol=1e-6 V_AbsTol=1e-6
I_RelTol=1e-7 I_AbsTol=1e-7

ForceM_Params=yes
NumDie=if(Number_of_Die>=0||Number_of_Die<=2) then Number_of_Die else 1 endif

NEW_CTH=if(CTH==-1) then -1 else (CTH/NumDie) endif
