Problem Title:
Foundation simulator does not properly simulate the CK_DIV or OSC52
symbols



Problem Description:
Keywords: Foundation, 5200, simulation, ck_div, osc52

Urgency: Standard


Solution 1:

The CK_DIV and OSC52 symbols cannot be simulated
because thier functionallity depends on the attributes
divide1_by and divide2_by.  These attributes are defined by
the user and therefore, no simulation models can be made.

When doing functional simulation in the Foundation Logic
Simulator, if the mode is changed to TM, an arbitrary frequency
is applied to the two clock outputs.  These clocks are not
correlated to the input clock.

For simulation purposes the best thing to do is to apply the
stimulus directly to the outputs of the CK_DIV or OSC52
component.
