ok guys this topic got its answers!
nw that i have finally done the SIM...
here is the program schematics for spice3 if ne 1 ever searches for it... elctro-tech-online will be the only place that will have it..
spice3 code for SRAM module (6 transistors), based on berkeley transistor model for 35nm structure:
MODULO_SRAM
.include c:\gabriel\spice\ams35ps.lib
Va VDD 0 5
Vb IN 0 pulse(0, 5, .3ns, .5ns, 10ns 20ns)
M1 VDD IN OUT VDD MODP L= 0.6u W= 4.2u
M2 0 IN OUT 0 MODN L= 0.6u W= 1.4u
M3 VDD OUT IN VDD MODP L= 0.6u w= 4.2u
M4 0 OUT IN 0 MODN L= 0.6u W= 1.4u
Ca OUT 0 10ff
.TRAN 1p 40n
.print TRAN V(IN) V(OUT)
.probe
.END
also i would like to thanks sceadwain and fusionITR cuz without their answers i wouldnt have took the point of it =]
see ya
