I encounter a sopcbuilder problem

The problem with parameters inside your verilog source during sopc component generation is not new (but mostly fixed)

if you add a source.v as a hdl file inside the sopc component editor then in priviously versions you couldn't have a struct like

mymodule ( .... );

parameter EnableLCD = 1;

quartus itself can deal with such parameters, but during sopc component editor this was not possible. i had to remove such parameters, do the sopc job and then re-add the parameter.

Quartus 6.1 and Quartus 7.0 can handle such parameters.
