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. WebJul 25, 2024 · The Verilog-2005 specification also calls a one-dimensional array with elements of type reg a memory. It is useful for modeling memory elements like read-only memory (ROM), and random access memory (RAM). Verilog arrays are synthesizable, so you can use them in synthesizable RTL code. colorado mining association websiteWebA widely-accepted guideline for synthesis and reusability is that all RTL module outputs should be registered. If one or more outputs cannot be registered, then either the module boundary or the location of that combo logic should be reconsidered. For an async module such as this, the synchronizers can serve as the output regs. dr scott murray
