The GTKRO high speed serial data receivers have been so far tested by generating 3.2Gbps serial streams on board and looping them back, as during the Nov 2013 dry run.

The simulated data pattern matches the pattern (idle characters) published by Matt.

Stricter check could be done by testing the GTKRO against an up-to-date model of the TDCpix serializer.

The GTKRO serial configuration link has been so far tested by hosting in the GTKRO FPGA both the slow link controller and a simulated TDCpix-side endpoint.

The loopback through the installed fibers has been tested during the Nov 2013 dry run.

The GTKRO controller has been checked against Matt’s up-to-date model of the TDCpix configuration link controller. The simulation results shows that the two system properly exchange data.

The higher level of the TDCpix configuration protocol could be handled locally by the on board NIOS processor which has access to:

• on-board SRAM 1M x 18bit for local configuration variable storage (SRAM interface module developed by R.Malaguti, INFN-FE)

• FIFO based interface to the “hardware” layer of the TDCpix configuration protocol

• Stefano’s ethernet MAC

• I2C link (firmware developed by R. Malaguti, INFN-FE) to on board sensors (XCVR link input optical power; FPGA temperature)
