LogiCORE FIR Compiler v1.0 or v2.0 and 8.1 or 8.2 NGDBuild - Single rate MAC FIR filter fails to generate, empty or missing netlist, and "ERROR:sim - NgdBuild:153" or "ERROR:NgdBuild:604"


Why does my single rate MAC FIR filter fail to generate, giving me an empty or missing netlist, and the following errors:

"ERROR:sim - NgdBuild:153"



Example 1:

ERROR:sim - NgdBuild:153 - The input EDIF file

"proj/tmp/_cg/m5_multi_sr_80622_18_fir_compiler_v1_0_xst_1_mac_fir_v5_1_xst.edn" is empty!

ERROR:sim - NgdBuild:276 - edif2ngd exited with errors (return code 2).

Example 2:

ERROR:NgdBuild:604 - logical block


_mac5' with type

'm5_multi_sr_80622_18_fir_compiler_v1_0_xst_1_mac_fir_v5_1_xst' could not be

resolved. A pin name misspelling can cause this, a missing edif or ngc file,

or the misspelling of a type name. Symbol

'm5_multi_sr_80622_18_fir_compiler_v1_0_xst_1_mac_fir_v5_1_xst' is not

supported in target 'spartan2'.


This should only occur for non Virtex-4 AND Virtex-5 cores.

This is resolved in v2.0 of the FIR Compiler.
