5 Concurrent Constructions Concurrent VHDL statements are \executed" continuously, and corresponds to combinational logic. 5.1 When-Else: Multiplexer Net The syntax for the when else assignment is fresg<= fval1gwhen fcond1gelse fval2gwhen fcond2gelse else fvalNg; If fcond1gis true, then fresgis assigned the value fval1g.

SEQUENTIAL AND CONCURRENT STATEMENTS IN THE VHDL LANGUAGE A VHDL description has two domains: a sequential domain and a concurrent domain. The sequential domain is represented by a process or subprogram that contains sequential statements. These statements are exe- All concurrent statements in an architecture are executed simultaneously. Concurrent statements are used to express parallel activity as is the case with any digital activity. Concurrent Statements are executed with no predefined order by the simulator. So the order in which the code is written does not have any effect on its function. In VHDL, there are two different concurrent statements which we can use to model a mux.

– Can have multiple process blocks in an architecture. In the conditional signal assignment, you need the else keyword. More code for the same functionality. Official name for this VHDL when/else assignment is the conditional signal assignment b <= "1000" when a = "00" else "0100" when a = "01" else "0010" when a = "10" else "0001" when a = "11"; 7 Concurrent Statements A VHDL architecture contains a set of concurrent statements.

In VHDL, there are two different concurrent statements which we can use to model a mux. The VHDL with select statement, also commonly referred to as selected signal assignment, is one of these constructs. The other method we can use to concurrently model a mux is the VHDL when else statement.

This le is down- for concurrent activities, such as task execution).
