• 6739 - CrossLink-NX: There is described that "VCCM is an internal supply that is derived from VCCAUX and should measure around 1.25 V", What can we check with VCCM?

  VCCM is an internal supply, and it is embedded in the silicon which does not have a connection to the pin. The available pins are enumerated in Section 5.2 of FPGA-DS-02049 or Crosslink-NX Family. Hence, we cannot monitor or access VCCM.

• 6159 - CrossLink: VCCIO0 is up first and internal power good will wait for VCC and VCCaux. Based on the power sequence for Crosslink based on PCN04A-20, does it have a risk of configuration issues or power-up?

  Since they already have VCCIO0 (3.3V) powered up first, that part should not be an issue. VCCIO0 is the most important VCCIO to be powered up first. The main reason for the change is that we found VCCaux needs to be powered up last or Crosslink may ...
