'''Q: How do I get port dimensions?'''

A port can have multiple (packed/unpacked) dimensions like "module test (input [1:0][2:3] in1 [4:5][6:7]);". Below is a code excerpt in C++:

Array *port_arr = vgModule->GetPorts();
VeriIdDef *port_id ;
unsigned i;
FOREACH_ARRAY_ITEM(port_arr, i, port_id) {
if (!port_id) continue ;
char* name = port_id->GetName();
unsigned j=0 ;
VeriRange *dim ;
while (dim = port_id->GetDimensionAt(j++)) {
VeriExpression *left = dim->GetLeft() ; // Left range bound
VeriExpression *right = dim->GetRight() ; // right range bound
}
}

For array (e.g. "module test (input [15:0] in1);"), it's sufficient to call GetDimensionAt(0) instead of the FOREACH loop as above.
