5.5.2.1 Declaration Of ChipScope Core in VHDL

The ChipScope core is simple to use. Just connect up the signal for observation to the data ports,

the trigger signals to trigger and the clock. The number of ports and triggers is defined when you

create the debug core in the ChipScope tool. The clock is used as the sample clock for the logic

analyzer, so you must use a clock that is higher frequency than the signals you wish to observe.

Here’s a core we used in debug shown below.
