HPS Trace Timing Characteristics

Table 81.  Trace Timing Requirements

To increase the trace bandwidth, Intel recommends routing the trace interface to the FPGA in the HPS Platform Designer component. The FPGA trace interface offers a 64-bit single data rate path that can be converted to double data rate to minimize FPGA I/O usage.

Depending on the trace module that you connect to the HPS trace interface, you may need to include board termination to achieve the maximum sampling speed possible. Refer to your trace module data sheet for termination recommendations.

Most trace modules implement programmable clock and data skew, to improve trace data timing margins. Alternatively, you can change the clock-to-data timing relationship with the HPS programmable I/O delay.
