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;

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();

}
