Interrupt Configuration window

In this section:

What do you want to do?

The Interrupt Configuration window is available by choosing Simulator>Interrupt Configuration.

InterruptConfigWin_Mym80_1.png

This window lists all installed interrupts. Use this window to enable or disable individual interrupts or the interrupt simulation system, and to edit the properties of installed interrupts.

Requirements

The C-SPY simulator.

Display area

This area contains these columns:

Interrupt

Lists all installed interrupts. Use the checkbox to enable or disable the interrupt.

ID

A unique interrupt identifier.

Type

Shows the type of the interrupt. The type can be one of:

Forced, a single-occasion interrupt defined in the Available Interrupts window.

Single, a single-occasion interrupt.

Repeat, a periodically occurring interrupt.

If the interrupt has been set from a C-SPY macro, the additional part (macro) is added, for example: Repeat(macro).

Description

A description of the selected interrupt, if available. The description is retrieved from the selected device description file. See this file for a detailed description. For interrupts specified using the system macro __orderInterrupt, the Description box is empty.

First Activation

The value of the cycle counter after which the specified interrupt will be generated. Click to edit.

Repeat Interval

The periodicity of the interrupt in cycles. Click to edit.

Hold Time

How long, in cycles, the interrupt remains pending until removed if it has not been processed. Click to edit. If you specify inf, the corresponding pending bit will be set until the interrupt is acknowledged or removed.

Variance %

A timing variation range, as a percentage of the repeat interval, in which the interrupt might occur for a period. For example, if the repeat interval is 100 and the variance 5%, the interrupt might occur anywhere between T=95 and T=105, to simulate a variation in the timing. Click to edit.

Probability %

The probability, in percent, that the interrupt will actually occur within the specified period. Click to edit.

Context menu

This context menu is available:

InterruptConfigWin_PopUp_Mym80_1.png

These commands are available:

Enable Interrupt Simulation

Enables or disables the entire interrupt simulation system. If the interrupt simulation is disabled, the definitions remain but no interrupts are generated. Note that you can also enable and disable installed interrupts individually by using the check box to the left of the interrupt name in the list of installed interrupts.

Enable

Enables or disables the individual interrupt you clicked on.

Remove

Removes the individual interrupt you clicked on.

Add Interrupt

Selects an interrupt to install. The drop-down list contains all available interrupts. Your selection will automatically update the Description box. The list is populated with entries from the device description file that you have selected.

Remove All

Removes all installed interrupts in the window.

Open Available Interrupts Window

Opens the Available Interrupts window, see Available Interrupts window.
