ARRIA10 GX calibration issue - Manual says 2 things one versus other ... (?)

Hello Sree,

I managed to solve, the solution is explained in chapter 6.14 of the User Manual Intel arria 10 Transceiver PHY,

It says:

Figure 280. Independent Instances of Simplex TX/RX in the Same Physical Location

Rules for Merging Reconfiguration Interfaces Across Multiple IP Cores

To merge reconfiguration interfaces across multiple IP blocks, you must follow these rules:

1. The control signals for the reconfiguration interfaces of the IP blocks must be driven by the same source. The reconfig_clk, reconfig_reset, reconfig_write, reconfig_read, reconfig_address, and reconfig_writedata ports of the two interfaces to be merged must be driven from the same source.

2. You must make a QSF assignment to manually specify which two reconfiguration interfaces are to be merged.

a. Use the XCVR_RECONFIG_GROUP assignment.

b. Set the To field of the assignment to either the reconfiguration interfaces of the instances to be merged or to the pin names. The reconfiguration interface has the string twentynm_hssi_avmm_if_inst.

c. Assign the two instances to be merged to the same reconfiguration group.

You cannot merge multiple reconfiguration interfaces when NPDME, optional reconfiguration logic, or embedded reconfiguration streamer are enabled in the Native PHY IP core. (63) You cannot merge the TX and RX channels when the Shared reconfiguration interface parameter is enabled in the Native PHY IP core Parameter Editor.

You can merge channels only if the reconfiguration interfaces are independent.

I applied this and now the compilation is ok and i can recalibrate the transceiver, just i can only write and not read the reconfiguration interface but it is ok the same.

Thanks

Best regards
