LogiCORE IP Serial RapidIO Gen2 v1.3 - Disabling the "Source Maintenance Support" option not supported

描述

When the option "Source Maintenance Support" is disabled in the Core Generator GUI while generating the core, the following errors are reported when implementingLogiCORE IP Serial RapidIO Gen2 v1.3 designs.

ERROR:MapLib:979 - LUT5 symbol

"srio_dut_inst/srio_wrapper_inst/cfg_fabric_inst/cfgb_awvalid_glue_set"

(output

signal=srio_dut_inst/srio_wrapper_inst/cfg_fabric_inst/cfgb_awvalid_glue_set)

has input signal "srio_dut_inst/srio_wrapper_inst/cfgr_awvalid" which will be

trimmed. See Section 5 of the Map Report File for details about why the input

signal will become undriven.

ERROR:MapLib:979 - LUT6 symbol

"srio_dut_inst/srio_wrapper_inst/cfg_fabric_inst/cfgl_arvalid_glue_set"

(output

signal=srio_dut_inst/srio_wrapper_inst/cfg_fabric_inst/cfgl_arvalid_glue_set)

has input signal

"srio_dut_inst/srio_wrapper_inst/cfg_fabric_inst/read_bar_hits<1>" which will

be trimmed. See Section 5 of the Map Report File for details about why the

input signal will become undriven.

解决方案

The ability to disable "Source Maintenance Support" in the Coregen GUI is currently not supported. To implement the design without errors, this option should always be enabled. This issue will be fixed in a future release of the core. If a user wants to disable sourcing transactions and save resources, they can just tie the MAINTR inputs to 0 and let MAP trim the unused logic during implementation.
