The CASE statement is generally synthesisable. With repeated assignments to a target signal, it willsynthesise to a large multiplexer with logic on the select inputs to evaluate the conditions for the different choices in the case statement branches. No … VHDL Processes VHDL Sensitivity List. When we write a process block in VHDL, each line of the code is run in sequence until we get to Simple VHDL Process Example.

I have written VHDL code for VGA controller for spartan 3E board. The code simulates and works well without the reset and clk process in the code below. But after inserting the process(reset,clk) the h_count and v_count counters stop counting and are driven to XXXXX undefined in simulation. The range may be any discrete range, e.g. an enumerated type: type PRIMARY is (RED, GREEN, BLUE); type COLOUR is ARRAY (PRIMARY) of integer range 0 to 255; -- other statements MUX: process begin for SEL in PRIMARY loop V_BUS <= VIDEO(SEL); wait for 10 ns; end loop; end process MUX; Tutorial - Sequential Code on your FPGA Using Process (in VHDL) or Always Block (in Verilog) with Clocks.

VHDL – combinational and Note: Signals are set when the process terminates Combinational logic and. ”process”. Remember to include all inputs in the.

Double In VHDL, sensitivity list is ignored while synthesis. The hardware synthesised depends only on how you described it inside the process block.

The process statement can also contain signal assignments in order to specify the outputs of the process. Our first example of the process statement is trivial and would not normally be done in a process statement. However, it allows us to examine the process statement without learning any sequential statements first.
