SIMULATION, DCM - CLKDV output aligns with the falling edge of CLK0 instead of the rising edge of CLK0

Description

The clock divide output (CLKDV) aligns with the falling edge of CLK0 instead of the rising edge of CLK0 (this has only been observed when the DCM reset pulse is asserted for less than one clock cycle).

Solution

To avoid this problem, always assert the DCM reset for more than one clock cycle.
