PTP/gPTP Verification IP

Truechip's PTP/gPTP Verification IP provides an effective & efficient way to verify the components interfacing with PTP/gPTP interface of an IP or SoC. Truechip's PTP VIP is fully compliant with IEEE 1588-2008 specification and gPTP VIP is fully compliant with IEEE 802.1AS-2011 specification. This VIP is lightweight with an easy plug-and-play interface so that there is no hit on the design cycle time.
