The SI list is not the hotline for vendors tools.
Call Synopsys.

 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
