LogiCORE IP Serial RapidIO Gen2 v3.2 - HELLO Format support in example design simulation

描述

Version Found: 3.2

Version Resolved and other Known Issues: (Xilinx Answer 54648)

During example design simulation, when Initiator/Target Legacy is chosen as the Port I/O Style, the tool returns the following error message:

# ** Fatal: (vsim-3363) ./../../../srio_no_hello_msg_default_example.srcs/sources_1/ip/srio_no_hello_msg_default/synth/srio_no_hello_msg_default_block.v(945): The array length (8) of VHDL port 's_axis_iotx_tuser' does not match the width (32) of its Verilog connection (11th connection).

# FATAL ERROR while loading design

A similar issue is observed when Condensed I/O is chosen as the Port I/O Style.

The error message only occurs when the 'HELLO Format' option is de-selected in the core configuration GUI.

解决方案

This is a known issue which is due to be fixed in a future release of the core.

Currently, example design simulation without the "HELLO format" option is not supported.

The error only occurs with some third party simulators, for example Questa, but not with Vivado XSIM. To work around it, you can run post-synthesis simulation in Questa.

Note: "Version Found" refers to the version where the problem was first discovered.

The problem might also exist in earlier versions, but no specific testing has been performed to verify earlier versions.
