Time-stamped switching information on signals in a design recorded during a simulation. (Note: To get credit for this problem the student must have the word “time-stamped” (or some other related term) to indicate not only signal transitions are recorded but the time those transitions occurred are also recorded.) 3. (2 points) FPGAs are often soldered on a PCB, which fixes which pins are used

Unformatted text preview: for I/O. How is the synthesizer informed of these pin assignments so the FPGA can be properly programmed? Pin assignments are provided by the user either manually during the synthesis process or via a user constraint file. 4. (2 points) How do ports in modules differ from ports in tasks? Ports in tasks are used to pass values; ports in modules are signals used for interfacing. 5. (2 points) How do you make a task re-entrant? After the keyword “task” you put the keyword “automatic”...
