NAME
GENLIB_ELM - Creates a single element bus name for netlist
SYNOPSYS
#include <genlib.h> char ∗GENLIB_ELM(busname, index); char ∗busname; long index;
PARAMETERS
- busname
-
Common signal name for a bus
- index
-
Index of the demanded signal belonging to the bus
DESCRIPTION
ELM Creates a single element bus names valid for the genlib netlist functions that manipulate the signal, and/or connector, concept. They are:
LOINS(3)
LOCON(3)
The index argument gives the index of the name to be created.
This function has a constant equivalent, it means that if the index value is known at compilation time, one should better use, for readability purposes, the "[n]" construct.
EXAMPLE
#include <genlib.h>
main()
{
int b = 0;
int e = 12;
/∗ Create a figure to work on ∗/
GENLIB_DEF_LOFIG("mycell");
/∗ define interface ∗/
GENLIB_LOCON(GENLIB_BUS("i", b, e), INPUT, BUS("sig", b, e);
GENLIB_LOCON("o[2:0]", OUTPUT, "sigout[4:6]");
/∗ Place an instance ∗/
GENLIB_LOINS("model","instance", GENLIB_ELM("sig", e/2), "sigout[6]", EOL);
/∗ Save all that on disk ∗/
GENLIB_SAVE_LOFIG();
