3.1i NGDBuild, EXEMPLAR - "ERROR:NgdBuild:432 - logical block 'TIMING_REF_INST/ix11' with type 'FALSE' (or 'TRI' or 'DFFRS') is unexpanded.
General Description: With an EDIF netlist generated from Leonardo Spectrum, running the Translate (NGDBuild) phase results in errors similar to the following:
ERROR:NgdBuild:432 - logical block 'ex_1' with type 'FALSE' is unexpanded ERROR:NgdBuild:432 - logical block 'ex2/reg2' with type 'DFFRS' is unexpanded ERROR:NgdBuild:432 - logical block 'ex3/tri_sync' with type 'TRI' is unexpanded
ソリューション
This usually happens when the EDIF netlist is written out without running the 'OPTIMIZE' step in Leonardo Spectrum. The 'OPTIMIZE' step will map the Leonardo Spectrum components into the appropriate Xilinx device primitives.
The following is an example of a complete TCL script:
set part v50ecs144 load_library xcve read ./example.vhd optimize -target xcve auto_write example.edf
NOTE: If you are using the GUI Quick Setup flow, the 'OPTIMIZE' step will be automatically run by the software.
