Instruments PAL circuit. A PAL is a type of field-programmable
PLA. See page 5 for the circuit diagram. Pins 1-9 and 11 are
inputs; pins 12 and 19 are outputs; pins 13-18 can be used as either
inputs or outputs; pins 10 and 20 (not shown on logic diagram) are
ground and power.
- PathSim simulator
for the simple implementation shown in Figure 4.2. This simulator
runs in a browser window and works on Windows, Mac, or Linux.
Create a convenient folder on your computer into which to unpack it,
and then open the file
PathSim.html with your favorite
browser. Be sure to click on About PathSim to read how to
use it. Some additional hints: After you unpack the files, on Linux
and other systems where filenames are case-sensitive, rename
HelpFiles/PathSim.jpg
to HelpFiles/pathsim.jpg. If you don't see the circuit
diagram initially, reload the page. When inputting instructions,
data, or registers, the last line entered should have a blank space
at the end. Otherwise you may get spurious error messages.
