LogiCORE 1-D Discrete Cosine Transform (DCT) v2.1, 5.2is3 NGDBuild, XST - 1-D DCT COREGen netlist merge creates NGDBuild 604 error

Description

Keywords: NGD, build, 2D, discrete, cosine, transform

Urgency: Standard

General Description:
When I use the 1-D Discrete Cosine Transform v2.1 and instantiate it in my source code, translate fails with the following error:

"ERROR:NgdBuild:604 - logical block 'dct_left' with type 'DA_1D_DCT' 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 'DA_1D_DCT' is not supported in
target 'spartan2e'"

Solution

To resolve this issue, disable the "Read Cores" option within the synthesis properties. For XST, select Synthesis options -> Read Cores to disable this option.
