Raypfaff Posted February 26, 2013 Report Share Posted February 26, 2013 I've gone through some of the basic tutorials for writing in VHDL and I decided to play around with the open souce bitcoin miner. Before the thread gets hijacked, yes I know I will make no money. It's just a fun little project. When I try to create a program using the ISE Webpack tool, I get the following warnings/errors. NgdBuild:486 - Attribute "FACTORY_JF" is not allowed on symbol "dcm" of type "DCM_BASE". This attribute will be ignored.WARNING:NgdBuild:486 - Attribute "PHASE_SHIFT" is not allowed on symbol "dcm" of type "DCM_BASE". This attribute will be ignored.WARNING:NgdBuild:486 - Attribute "STARTUP_WAIT" is not allowed on symbol "dcm" of type "DCM_BASE". This attribute will be ignored.ERROR:NgdBuild:604 - logical block 'dcm' with type 'DCM_BASE' could not be resolved. A pin name misspelling can cause this, a missing edif or ngc file, case mismatch between the block name and the edif or ngc file name, or the misspelling of a type name. Symbol 'DCM_BASE' is not supported in target 'spartan3e'. There are, I think, several more warnings having to do with DCM_BASE. I "think" that the problem is that DCM_BASE really needs to be DCM. However, I can't find the definition of DCM_BASE in either the VHDL or in the .ucf file. Does anyone have any idea what the problem here might actually be?
