I have some question about spectre format.

I want conversion of hspice format sub-circuit into spectre format sub-circuit.

.LIB LVAR_CAP
*                                                            
.subckt lvar_cap in out w=1 l=1 nf=1
.param  area='l*w'  peri='(2*l+2*w)'  pt='temper'
+       tc1aa=-1.7089E-4 tc1ab=-4.2154E-5 tc1ac= 3.8616E-3 tc1ad= 1.7499E-3
+       tc2aa= 3.692E-7  tc2ab=-3.553E-8  tc2ac= 6.1988E-7 tc2ad=-7.774E-7
+       tc1pa= 7.8389E-5 tc1pb= 1.4114E-4 tc1pc= 1.0051E-3 tc1pd= 3.9153E-3
+       tc2pa= 6.6065E-7 tc2pb=-4.2438E-7 tc2pc=-1.4547E-5 tc2pd=-8.3602E-7
+       cgmin_va= 1.8247E-3   dcg_va= 5.0975E-3
+       dvg0_va=-0.03757      vgnorm_va= 0.28668
+       cgmin_vp= 1.6237E-10  dcg_vp=-8.8928E-11
+       dvg0_vp= 0.04955      vgnorm_vp= 0.21354
+       cgmina='cgmin_va*(1+tc1aa*(pt-25)+tc2aa*(pt-25)*(pt-25))'
+       dcga='dcg_va*(1+tc1ab*(pt-25)+tc2ab*(pt-25)*(pt-25))'
+       dvg0a='dvg0_va*(1+tc1ac*(pt-25)+tc2ac*(pt-25)*(pt-25))'
+       vgnorma='vgnorm_va*(1+tc1ad*(pt-25)+tc2ad*(pt-25)*(pt-25))'
+       cgminp='cgmin_vp*(1+tc1pa*(pt-25)+tc2pa*(pt-25)*(pt-25))'
+       dcgp='dcg_vp*(1+tc1pb*(pt-25)+tc2pb*(pt-25)*(pt-25))'
+       dvg0p='dvg0_vp*(1+tc1pc*(pt-25)+tc2pc*(pt-25)*(pt-25))'
+       vgnormp='vgnorm_vp*(1+tc1pd*(pt-25)+tc2pd*(pt-25)*(pt-25))'
c  in out '(area*(cgmina+dcga*(1+tanh((v(in)-dvg0a)/vgnorma)))+peri*(cgminp+dcgp*(1+tanh((
v(in)-dvg0p)/vgnormp))))*nf'
.ends lvar_cap
*                                                            
.ENDL LVAR_CAP

I want to conversion functions above, is possible?

send your opinion, please... i'll wait. good bye

Best Regards

Also, the above subckt can be simulated directly in spectre with no syntax changes from IC5141 onwards. In IC5141, you need to do:

Code:

spectre +csfe netlist.hsp 

whereas in the latest simulator release, MMSIM60, the new front end (enabled by +csfe in IC5141) is on by default. The new front end gives improved performance (memory and speed) in the netlist parsing of spectre syntax, and also supports natively SPICE syntax files.

This is of course with Ken's proviso taken as read.

Andrew.
