The reg type can only be assigned a value in an always or initial block, and is used to apply stimulus to the inputs of the DUT. The wire type is a passive data type that holds a value driven on it by a port, assign statement or reg type.

The header file registers.svh contains macros that expand to descriptions of registers. To avoid misuse of always_ff blocks, only the following macros shall be used to describe sequential behavior. The use of linter rules that flag explicit uses of always_ff in source code is encouraged.

WebTherefore, with RTL coding registers, we need to apply constraints to the flop using the gtech (generic technology) cell or pin name. By definition, the cell name of the flop will always be its output signal name followed by _reg. In our example, the output signal name is called DIV_CLK, so the cell name of the flop will be called DIV_CELL_reg.
