Lattice Semiconductor
registers in the design are asynchronously set or reset by the same wire. The following examples show the correct
syntax for instantiating GSR in the VHDL and Verilog codes.
Use PIC Features
Using I/O Registers/Latches in PIC
Moving registers or latches into Input/Output cells (PIC) may reduce the number of PFUs used and decrease rout-
ing congestion. In addition, it reduces setup time requirements for incoming data and clock-to-output delay for out-
put data, as shown in Figure 13-11. Most synthesis tools will infer input registers or output registers in PIC if
possible. Users can set synthesis attributes in the specific tools to turn off the auto-infer capability. Users can also
instantiate library elements to control the implementation of PIC resource usage.
