Name

DP_MUX4CS - 4 input multiplexer.

Synopsys

#include <fpgen.h>

void DP_MUX4CS(
char *InstName, /* Instance name */ long Width , /* Number of bits */ long Slice , /* Index of the bottom slice */

char *BusSel , /* IN Input Select CTRL */ char *BusI3 , /* IN Third Input DATA */ char *BusI2 , /* IN Third Input DATA */ char *BusI1 , /* IN Second Input DATA */ char *BusI0 , /* IN First Input DATA */

char *BusO
, /* OUT Direct Result Output DATA */ EOL);

Description

DP_MUX4CS creates a 4 input multiplexer. It is build using a dual-CMOS architecture. The signal BusSel select which input is connected to the output :
- BusSel equal 00":BusO <= BusI0. - BusSel equal 01":BusO <= BusI1. - BusSel equal 10":BusO <= BusI2. - BusSel equal 11":BusO <= BusI3. DP_MUX3CS build an operator of Width bits and then instanciates it with the name InstName. The maximal authorized value for Width is the full width of the current data-path, set by the previous call to the function DP_DEFLOFIG. In the layout the leaf cells are placed on the slices numbered from Slice to Slice+Width-1 (the bottom slice of the whole data-path is numbered zero).

Characteristics

Operator wide : 60 lambdas.

Example

DP_MUX4CS("mux4cs_instance0", 32,
0, bus_sel[1:0] , input_i3[31:0]", input_i2[31:0]", input_i1[31:0]", input_i0[31:0]", output_o[31:0]", EOL);
