The
Interrupt/DMA
window displays the current status of the interrupt
inputs of the CPU model (ISS) an shows the current
status of DMA channels.
The processor
model (ISS) contains interrupt input signals with the
following features:
Connect an HDL output signal to the interrupt input
Add a signal generator to the interrupt input
Manually change the interrupt input in the Interrupt/DMA
window
Yet another method of generating interrupts is to
automatically force an interrupt on user specified
events. Questions like: "What happens if an interrupt
occurs when the CPU executes this specific instruction
or reads from this peripheral address?" are easily
tested. Interrupts can be user defined to occur on
program execution (on address level basis) and on
reading or writing registers and/or memory locations.
