# Hspice subckt naming convention

I have a subckt def:

.subckt test_L1.2u_W0.14u x y
. . . . . .
.ends test_L1.2u_W0.14u


I define another subckt which calls the above subckt test_L1.2u_W0.14u

.subckt top
Xt1 x1 y1 test_L1.2u_W0.14u
Xt2 x2 y2 test_L1.2u_W0.14u
.ends top


The error notifies that test_L1.2u_W0.14u did not exist.

I create a testbench in which remove the . In the subckt definition, and it runs without error. So does hspice care about . In naming convention of subckt. If so, could you provide me some docs relating to this?

However, what is a delimiter is left to your imagination. You have just found that . is a delimiter.
