Low Voltage GreenPAK Programmable

Mixed-Signal Matrix

Preliminary

As shown in Figures 22-28 there is a possibility to use LUT/DFF and CNT/DLY simultaneously.

Note: It is not possible to use LUT and DFF at once, one of these macrocells must be selected.

 Case 1. LUT/DFF in front of CNT/DLY. Three input signals from the connection matrix go to previously selected LUT or DFF's

inputs and produce a single output which goes to a CND/DLY input. In its turn Counter/Delay's output goes back to the matrix.

 Case 2. CNT/DLY in front of LUT/DFF. Two input signals from the connection matrix go to CND/DLY's inputs (IN and CLK).

Its output signal can be connected to any input of previously selected LUT or DFF, after which the signal goes back to the

matrix.

 Case 3. Single LUT/DFF or CNT/DLY. Also, it is possible to use a standalone LUT/DFF or CNT/DLY. In this case, all inputs

and output of the macrocell are connected to the matrix.
