Symmetric Interpolation Filters That Use M20K Blocks for Data Storage in Stratix V Devices Fail

Description

Symmetric interpolation filters that target a Stratix V device and use M20K memory blocks for data storage fail in simulation or compilation.

Symmetric interpolation filters with multicycle variable structure and Data Storage set to M20K that target a Stratix V device.

The Quartus II software cannot generate a netlist, or simulation fails due to a mismatch with expected results.

Resolution

For symmetric interpolation filters with multicycle variable structure that target a Stratix V device, set Data Storage to Auto.
