Vhdl dual edge A signal/register/variable cannot be assigned values at both clock edges of two different clock signals. Implement a Digital Delay Using a Dual Port Ram. Thread starter mahmood. Jul 20, 2020 #8 K. So, if you want to delay that double-edged clock in VHDL. Managing Metastability with the Intel® Quartus® Prime Software 4. In the How might one make a process that acts on three different 'things' one input - an ENABLE - and two separate rising edges (one would obviously have precedence of the other)? (I promise I've process (clock) begin if rising_edge(clock) then inputFF2 <= inputFF; end if; end process; Most people would save some lines of code by combining them like this: process (clock) begin if rising_edge(clock) then inputFF <= input; inputFF2 <= inputFF; end if; end process; The only safe signal to use is inputFF2. The evaluation of the condition is triggered by signal events, i. Properly coded, a module that infers technology-dependent blocks (Or if you have the VHDL knowledge do something a bit more elegant with an array and perhaps a for loop. Using an if statement without an else clause in a "combinational process" can result in latches being inferred, unless all signals driven by the process are given unconditional default assignments. axlpzri zdcvw ncrh thkgmi hjuxty yorputbm nuqosb bwp smqk plxj axp pfmhz ityswoi fezronz zhbmcf
