Hi everyone
I am running a project by use LTspice, and I want to varify the solution in hspice.
But when I run the hspice netlist which is transfered from the LTspice,threr are some error happened.

syntax error at or before "{Limit" "(" "V" "(" "nAmp" ")" "{VHigh}" "{VLow}" ")" "}"

and this is the hspice code:
"EOut N001 0 Value={Limit(V(nAmp),{VHigh},{VLow})}"
.Param VHigh=4V VLow=-4V

What should I do?


regards,
pohan

Welcome to EP!
Does the sim run without error in LTspice?
I don't know Hspice, but according to an Hspice guide, a behavioural voltage source has the syntax :
Exxx n+ n- VOL=’equation’
+ <MAX=val> <MIN=val>

It is possible that Hspice doesn't recognize this particular syntax for the voltage controlled voltage source. LTSpice has some extensions over classic Spice (as do many other Spice derivatives).

LTSPICE help states:'Syntax: Exxx n+ n- value={<expression>}
This is an alternative syntax of the behavioral source, arbitrary behavioral voltage source, B.
'

Try to replace Eout by Bout to see whether this is recognized by Hspice.
