7.3 I/O Port Usage
7.4 Example Session Using ZISIM
ZISIM400 models serial I/O as a memory-mapped device. Programs
perform terminal I/O by reading from and writing to the appropriate
address locations. The simulator defines two serial ports and one host
processor interface (HPI) port. Each port has a transmit buffer and a
receive buffer.
corresponding files for the I/O ports for the LSI402ZX, LSI403Z, and
ZSP400-core based devices.
Table 7.9
The format of input and output files is the same. Data must be in decimal
digits, with each data on a single line. If the input file is not present in
the current running directory at the time of the request, the simulator
prints an error message to standard output and exits.
This section contains an example simulation session using ZISIM400 in
interactive mode. A simulation session using zisim for other architectures
is similar.
In the example simulation, demo.exe is invoked using the -t (enable
trace) command-line option. Trace information is displayed in five fields:
