But the VHDL 2008 standard now lets you do this: process(all) VHDL Online Help - Sensitivity List - vhdl.renerta.com . Jul 19, 2012 #4 D. dave_xenos Newbie level 1. Joined Jul 19, 2012 Messages 1 Helped 0 Reputation 0 Reaction Learn how to wake up a process in VHDL using a sensitivity list. Use signals to trigger processes to wake up.

VHDL-87 I have read in a vhdl book that if the sensitivity list in vhdl process is left blank the process executes indefinitely but if i leave the sensitivity list blank, the xilinx synthesize tool shows error.So i put a dummy input bit signal in the sensitivity list and as far as i know the process executes only when there is a event on the sensitivity list.But in modelsim it takes by default the value as 0 for this bit signal and then even if dont change it's value the simulation works correct and sensitivity list. Hence, VHDL processes give you the control. Quote: > In my dream world all the HDLs would be as follows: > 1.

If any of the signals change, the process will wake up, and the code within it is executed. A process with a sensitivity list cannot also contain wait statements.

The VHDL language defines that a process with a sensitivity list cannot contain WAIT statements. Therefore it is a shorthand way of writing a PROCESS with a signal WAIT statement at the bottom which waits for an event on one or more of the signals in the sensitivity list of its equivalent.

Which of the following line of the code contains an error? VHDL Example - Wait Statement. The Wait Statement is a powerful tool in VHDL. It can be used in both synthesizable and non-synthesizable code, but is more often used in test benches and models. Wait can be used in the following ways: wait until condition wait on sensitivity list wait for time expression Processes with sensitivity lists will not execute again until there is an event on one of the signals in the sensitivity_list.

The use of IEEE.std_logic_1164.all is also required before the entity, like: library IEEE; use IEEE.std_logic_1164.all; entity lab2 is The first IEEE.std_logic_1164.all only applies to the package, and package body of the same package, but not to any other design objects like an entity or package, even if these happens to This thread is about the vhdl process sensitivity list and how to avoid simulation problems if I use it for anything other than the clock or reset inputs. Googling 'VHDL sensitivity list' and reading I see comments like this: --- Quote Start --- Also, the synthesis tools (talking about the Xilinx XST in this case) don't necessarily always respect the process sensitivity list. 4. The code given below is a VHDL implementation of _____ ARCHITECTURE my_circuit OF my_logic IS BEGIN WITH ab SELECT y <= x0 WHEN “00”; x1 WHEN “01”; x2 WHEN “10”; x3 WHEN “11”; END my_circuit; a) 4 to 1 MUX b) 1 to 4 DEMUX c) 8 to 1 MUX d) 1 to 8 DEMUX. 5.

Each concurrent statement IEEE VHDL does not allow a sensitivity list if the process has a wait Figure 3: A VHDL entity consisting of an interface (entity declaration) and a body The sensitivity list is a set of signals to which the process is sensitive. 139. 5.2.2 wait on sensitivity_list. The wait on sensitivity_list suspends a process until the occurrence of another event on one of the signals in the sensitivity list.
