In response, there have been many changes to VHDL. Although the base
language has remained relatively stable, with the only changes being a
reworking of the shared variables of VHDL-93 and a number of bug fixes and
other, minor ...
This means that it will resume on changes on either data input, even though only
one of them is selected at any time. If we are concerned about this slight lack of
efficiency in simulation, we can write the process differently, using wait ...
true when the wait statement is executed, the process will still suspend until the
appropriate signals change and cause the ... When clk changes to '1', nothing
happens, but when it changes to '0' again, the process resumes and schedules ...
A process to model a transmission line with delay 500 ps is transmission_line :
process (line_in) is begin line_out <= transport line_in after 500 ps; end process
transmission_line; In this model the output follows any changes in the input, but ...
