5.1. Synchronous Reset Synchronizer Parameterizable Macro (ipm_cdc_sync_rst)

The synchronous reset synchronizer parameterizable macro (ipm_cdc_sync_rst) synchronizes a synchronous reset signal to the destination clock domain. The generated output both asserts and de-asserts synchronously to the destination clock domain. The number of the synchronizer stages is configurable, allowing a range from three to ten stages. The default reset type is ACTIVE_HIGH, but you can specify the ACTIVE_HIGH or ACTIVE_LOW type of the reset signal with the RST_TYPE parameter.
