String Operator on If Expressions
String Operator on If Expressions
It is possible to use C-like functions strcmp and strncmp inside if statements used for netlist
configuration. strcmp and strncmp return “0” when the string matches, “not 0” otherwise.
Examples:
.param p1 = "myp1"
if (strcmp(p1,"myp1") == 0)
i1 1 0 1
else
i1 1 0 2
endif
r1 1 0 1
Here, i1 will be 1A.
if (strcmp($(p1),"myp1") == 0)
i1 2 0 3
else
i1 2 0 4
endif
r1 2 0 1
Similarly, i1 will be 3A because the if statement is true.

By default, (without the -E or -EE argument) Eldo understands the following simple preprocessor
commands: #if, #define , #undef , #ifdef , #ifndef
#else, #endif. These can be used as conditional statements to select a part of the netlist.
For example:
#define NO_RESISTOR
...
#ifndef NO_RESISTOR
R1 A B 1k
#endif
...
