+--managed to find a breach in seams!! Specifically with the code
+--generation of generics... so it is important to have it as part
+--of the test suite. The model is a small mesh ckt with 3 resistors
+--and 2 voltage sources.. simple nodal soln of the mesh is all that

+--This is a mixed signal model of an inverter... The input is a bit signal
+-- which is converted to a 5/0 value realSignal. This signal is then given

+-- then given to a atod... the final output is then a bit signal which is
+-- the inverse of the input bit signal...

+----------------------------------------------------------------------
+-- this is a test to check the corretness of the implemntation of the break
+-- statement and also the use of quantity port of type voltage.
+-- this is a vco model which first sets the initial condition
+-- using a break statement. Then again, a break statement is applied to keep
+-- the phase within 0-2pi. Thr output voltage eqn is obtained as vout and the
+-- phase eqn as phase'dot.

+-- REMARKS
+-- -------
+-- TESTED : Works great for freq of 1.0 KHz - 30.0MHz
+-- COMMENTS : The Values of R1_a and R1_b have to be 18.0k & 32.0K resp.
+-- The freq. is given by the equation
+-- F = 1/(2*PI*R*C)
+-- where R=R3=R4 and
+-- C=C3=C4.
