Watabou’s Medieval Fantasy City Generator.Is that if one or more of the arguments are forgotten in the sensitivity list,Ī new value for z is not recalculated if the forgotten argument changes. The risk of doing such continuous calculations in this way, The above will recalculate z when any of the values used in the calculationĬhanges, since all the arguments for calculating z are included in the Note that I removed the result variable, since the z output can just as If the process is rewritten to use a sensitivity list, it will be: alu_proc: process (sel, a, b) is The use of sensitivity list as equivalent to wait statement is also described After it has executed the last statement, the process suspends These signals changes value, the process resumes and executes the sequential This is a list of signals to which the process is sensitive. The process statement includes a sensitivity list after the keyword process. Which is a list of signals after the process keyword, thus not with theĪshendens book 3rd edition page 68 describes that a sensitivity list: However, the common way to write this for processes is with a sensitivity list, ´b´ to the wait statement, like: wait on sel, a, b The problem with the ALU process is that the wait on sel does not includeĪ and b, thus the process does not wake up and the output is not Am I missing something in the language or is my solution "correct"? Of course I can add an enable signal and have the process be sensitive to that but I think that should be told in the questions then. In the question I get the feeling that you should be able to do several additions sequentially, no subtraction between. Since it is sensitive to changes of the select bit I must do the functions sequentially, first an subtraction, then an addition then a subtraction again in the test bench. My issue has to do with the sensitivity list in the process. if the function select is '0', the ALU output should be the sum of the inputs otherwise the output should be the difference of the inputs."Ī <= 5 b <= 5 wait for 5 ns sel <= '1' wait for 5 ns Ī <= 10 b <= 5 wait for 5 ns sel <= '0' wait for 5 ns I'm trying to learn VHDL using Peter Ashenden's book 'The Designer's Guide to VHDL', but can't seem to shake the feeling that I have missed a fundamental item related to sensitivity lists.įor example a question is "Write a model that represents a simple ALU with integer inputs and output, and a function select input of type bit.
