normally, we would run simulations to catch them - except this is a
black-box.  and a pretty critical one.

i'm tempted to suggest bypassing the PLL - still including it - but
treating it entirely as a separate unit to which TestIssuer is **NOT**
connected.

instead the core is connected to the external sys_clk.

all PLL test signals still conected - just not the core to its output.
