7.1 EDK - "ERROR:MDT - dcm_module (dcm_0) - c:\project\system.mhs:xxx - not supported for architecture 'virtex'!"

Description

Keywords: DCM, Spartan-II, Spartan-2, Spartan-IIE, Spartan-2E, Virtex, Virtex-E, DLL, processor, MicroBlaze, MB

Urgency: Standard

General Description:
When creating a MicroBlaze design in a Virtex, Virtex-E, Spartan-II or Spartan-IIE, EDK will issue the following error message:

"ERROR:MDT - dcm_module (dcm_0) - c:\project\system.mhs:xxx - not supported for architecture 'virtex'!"

Solution

EDK automatically inserts a DCM module for every architecture that is supported in EDK. The DCM module will need to be removed if targeting a Virtex class (Virtex, Virtex-E, Spartan-II, Spartan-IIE) FPGA:

1. Select the pull-down menu Project -> Add/Edit cores.
2. Select the Peripherals tab.
3. Highlight the DCM module and push Delete.
4. Select the Ports tab.
5. Change the net attached to the 'sys_clk_pin' port from 'dcm_clk_s' to 'sys_clk_s'.
6. Push OK.
