Problem Title:
Foundation Simulator: high impedence on output of OSC4


Problem Description:
Keywords: osc4 simulate
Urgency: standard

General Description:
In the simulator, the output of the OSC4 symbol is always

Solution 1:

The OSC4 symbol is not simulatable in the Foundation

You must apply stimulus to the output(s) of the OSC4
(you can use the ready-made 50% duty cycle stimulators
for this).
