hi all
I created a PWL source in my main circuit but when I run the netlist with
hspice, it gives me error: **error** piecewise source 0:vdh
not increasing in time
I have tried many ways to modified it, but failed!
is there anybody meet the same problem like that? who can tell me where I am
making a mistake?
my netlist codes:
.tran 0.001n 18n UIC sweep DATA=INPUT_RAMP
options autostop accurat runlvl
ic v(dh)=vdd
........
param ckramp_l='9n-ckramp/2*1.25'
param ckramp_r='9n+ckramp/2*1.25'
param inramp_l='mid-inramp/2*1.25'
param inramp_r='mid+inramp/2*1.25'
.......
vsel sel 0 pwl (0n vdd 'ckramp_l' vdd 'ckramp_r' 0 13n 0)
vdh dh 0 pwl (0n vdd 'inramp_l' vdd 'inramp_r' 0 13n 0)
DATA INPUT_RAMP
inramp ckramp mid
0.015n 0.015n 13n
0.015n 0.015n 9n
0.015n 0.015n 5n
