3.2/3.1 EDK - MicroBlaze, MAP: "ERROR:Pack:679 - Unable to obey design constraints (MACRONAME=microblaze, RLOC=R-10C13.S0)"

描述

Keywords: configure, configuration

Urgency: Standard

General Description:
When I run an EDK MicroBlaze design in ISE, the following error occurs in MAP:

"ERROR:Pack:679 - Unable to obey design constraints (MACRONAME=microblaze,
RLOC=R-10C13.S0) which require the combination of the following symbols into
a single SLICE component:
FLOP symbol
"microblaze_comp/microblaze/microblaze_0_i_data_flow_i/pc_module_i/pc_bit_i10
/pc_if_dff" (Output Signal =
microblaze_comp/microblaze/microblaze_0_i_data_flow_i/pc_module_i/pc_bit_i10/
pc_if_dff)
FLOP symbol
"microblaze_comp/microblaze/microblaze_0_i_data_flow_i/pc_module_i/pc_bit_i11
/pc_if_dff" (Output Signal =
microblaze_comp/microblaze/microblaze_0_i_data_flow_i/pc_module_i/pc_bit_i11/
pc_if_dff)
LUT symbol
"microblaze_comp/microblaze/microblaze_0_i_data_flow_i/pc_module_i/pc_bit_i10
/newpc_mux" (Output Signal = microblaze_comp/ilmb_lmb_abus<10>)
LUT symbol
"microblaze_comp/microblaze/microblaze_0_i_data_flow_i/pc_module_i/pc_bit_i11
/newpc_mux" (Output Signal = microblaze_comp/ilmb_lmb_abus<11>)
Signal `microblaze_comp/ilmb_lmb_abus<10>' has a NOMERGE parameter. Please
correct the design constraints accordingly."

解决方案

The Translate option "Preserve Hierarchy on Submodule" can cause this error.

To resolve this issue, set the "Preserve Hierarchy on Submodule" option to "Off."
