LTPI IP - any plan to support OCP LTPI Revision 1.2? (MAX 10)
Hello,
On the current compliance baseline: the LTPI IP is compliant with OCP DC-SCM 2.1 LTPI revision 1.1, version 1.1 specifications, and for MAX 10 devices specifically, it supports up to 400 Mbps data rate for all speed grade configurations. LVDS Tunneling Protocol and Interface (LTPI) IP User Guide
On the Quartus Prime Standard Edition version that introduced MAX 10 support: LTPI IP v25.1 (Quartus Prime Standard Edition 25.1, dated 2025.11.03) added support for MAX 10 FPGAs. LVDS Tunneling Protocol and Interface (LTPI) IP v25.1
On the resource utilization reference: the LTPI IP resource utilization values for MAX 10 are obtained from Quartus Prime Standard Edition software version 25.1. LVDS Tunneling Protocol and Interface (LTPI) IP User Guide
Regarding the specific Revision 1.2 changes you mention — extended CRC/error handling, the new Frame Lost error, the LTPI Version → LTPI Revision rename, and the Link Speed timeout/Link Lost condition changes — none of those are documented in the available LTPI IP materials I have access to. I cannot confirm or deny a planned update.
