14 май 2017 The lecture is about procedures in VHDL: syntax, declaration, actual parameters, formal parameters, procedure overloading.

Now what I want is if an external signal, let's call it r_STOP gets asserted at any time, I want this procedure to exit immediately. Is there a nice way to do this? I was thinking that if this Verilog I could use fork/join_any to accomplish this, but there is no equivalent to fork and join in VHDL. Does anyone have any suggestions? A procedure call may be a sequential or a concurrent statement, which is based on where the actual procedure call statement is present. Functions are invoked by function call.

Procedure body defines the procedure's algorithm composed of sequential statements. When the procedure is called it starts executing the sequence of statements declared inside the procedure body. The procedure body consists of the subprogram declarative part After the reserved word is and the subprogram statement part placed between the reserved words begin and end.

If “clk_div_module” is even, the clock divider provides a Procedure creation and Procedure calls (example_vhdl) instantiation, add line 61 below, this will create a free running 20Mhz clock, but we need to supply a default value.

Form of procedure declaration: procedure procedure_name (formal-parameter-list) is.

The code within all subprograms is always executed sequentially. Procedures can feed back results to their environment via an arbitrary number of output parameters. However VHDL semantics don't allow you to read the output port C and hence you cannot implement such an expression.

Will always be wrong as it will be 'U' on each call of the procedure (I assume you're using VHDL 2008, as reading Outs is illegal in '93). You should declare set_reg_bus as inout to the procedure. If it's the value thats not updating, it might be because you have the value variable updated before the procedure is …

Procedures can feed back results to their environment via an arbitrary number of output parameters. However VHDL semantics don't allow you to read the output port C and hence you cannot implement such an expression. So what you can do is turn that port into a buffer port. Some people also make use in/out port for this purpose. But that makes thing complex. VHDL Compiler implements procedure and function calls with logic, unless you use the map_to_entity compiler directive (see ‘‘Mapping Subprograms to Components (Entities),” in Chapter 6).

Depending on their position within the VHDL code, either in an architecture or in a process, the procedure as a whole is executed concurrently or sequentially, respectively. The code within all subprograms is always executed sequentially. Procedures can feed back results to their environment via an arbitrary number of output parameters.
