Du har gedigna erfarenhet av: VHDL-design och FPGA-syntes Testmetodik i VHDL (simulering, testbänkar) Expert knowledge of Verilog and VHDL for FPGAs.

Important note: when several processes are run-able, the VHDL standard does not specify how the scheduler shall select which one to run. A consequence is that, depending on the simulator, the simulator's version, the operating system, or anything else, two simulations of the same VHDL model could, at one point, make different choices and select a different process to execute.

I usually never come across a with select statement. VHDL concurrent WITH-SELECT statement BNF and example is: with expression select. s <= waveform_1 when choice_list_1, waveform_2 when choice_list_2, waveform_n when choice_list_n; with alu_function select. alu_result <= op1 + op2 when alu_add | alu_incr, op1 – op2 when alu_subtract, VHDL står alltså för Very high speed integrated circuit Hardware Description Language.
