Hi,

Do you have an example of what you are trying to do?

You can embed if-else statements inside a subcircuit definition but, you
cannot embed a subcircuit definition within if-else statements.  For
example,

X1  D1 0 sub1 A=2
....
X2 D2 0 sub1 A=0

.subckt sub1 a b
.if (A > 0)
r1 a b 100
.else
r1 a b 100
c a b 10p
.endif

.ends

Has anyone expereinced problems with Hspice when chosing between different
subckts (to modify circuit topologies) using .IF statement?  And is there a
workaround (not using .Alter statement)?
