2.1.4 I/O Port Simulation

This section describes I/O port simulation executed by SOFTUNE Workbench.

■ I/O Port Simulation (Input Port)

There are two types of simulations in I/O port simulation: input port simulation, and output port simulation.

Input port simulation has the following types:

- Whenever a program reads the specified port, data is input from the pre-defined data input source.

- Whenever the instruction execution cycle count exceeds the specified cycle count, data is input to the

port.

To set an input port, use the [Setup] - [Debug Environment] - [I/O Port] menu, or the SET INPORT

command in the Command window.

Up to 4096 port addresses can be specified for the input port. The data input source can be a file or a

terminal. After reading the last data from the file, the data is read again from the beginning of the file. If a

terminal is specified, the input terminal is displayed at read access to the set port.

A text file created by an ordinary text editor, or a binary file containing direct code can be used as the data

input file. When using a text file, input the input data inside commas (,). When using a binary file, select the

binary radio button in the input port dialog.

■ I/O Port Simulation (Output Port)

At output port simulation, whenever a program writes data to the specified port, writing is executed to the

data output destination.

To set an output port, either use the [Setup] - [Debug Environment] - [I/O Port] menu, or the SET OUTPORT

command in the Command window.

Up to 4096 port addresses can be set as output ports. Select either a file or terminal (Output Terminal

window) as the data output destination.

A destination file must be either a text file that can be referred to by regular editors, or a binary file. To

output a binary file, select the Binary radio button in the Output Port dialog.

Note:

The following method is not supported by high-speed simulator debugger.

• Whenever the instruction execution cycle count exceeds the specified cycle count, data is input to

the port.

Furthermore the setting of memory map is necessary to set I/O port. When deleting memory map, I/O

port is also deleted.
