The System Console performs low-level hardware debugging of SOPC Builder systems. The System Console provides read and write access to the IP cores instantiated in your SOPC Builder system. You can use the System Console for the initial bring-up of your printed circuit board and low-level testing. The System Console is the appropriate tool for all of the following tasks:
- Verifying that the clock is toggling
- Verifying component pinouts
- Testing memories and peripheral devices
- Determining the value of the reset signal
