Syntax
4BIT_RING_COUNTER {[Subcircuit-label-n] [label-n]}
# Where, the Subcircuit labels are CNT, SET, RST, Q(0-3)
# All Subcircuit labels are mandatory
# Order is arbitrary
Example
4BIT_RING_COUNTER CNT clk RST rst SET set Q0 q0 Q1 q1 Q2 q2 Q3 q3
# CNT: Negative edge-triggered count input (clock),
# RST: Active-low asynchronous reset input,
# SET: Active-low asynchronous set input for the MSB position (Q3),
# Q(0-3): Sequence output
Generates the sequence of a 4-Bit Ring Counter timed by the clock input. Sequence is to be initated by activating the SET input for the MSB position (usually Ring count sequences consist of a single high bit, so the SET input is to be activated for a single clock edge).
