PDxxSIM I/O DLL Kit

Linkage Between the Simulator Engine and an I/O DLL

The simulator engine calls the functions that have been predefined on the I/O DLL side synchronously with the timing shown below:

• After executing one instruction (number of execution cycles)
• Before execution (PC value)
• When the target is reset
• When an interrupt occurs
• Immediately before memory read (address information)
• Immediately after memory write (address information)

Conversely, the following functions that have been made public for the simulator engine can be called from the I/O DLL side:

• Get memory contents
• Set a memory value
• Get a register value
• Set a register value
• Interrupt occurrence
• Confirm interrupt occurrence condition
• Inspect the total number of cycles executed
