Hello! I doing a design for an old system using Cyclone II device and developing with quartus 11 and sopc builder.
I have a verliog file <design.v> that use with component editor to create an IP. In this verilog file I use parameters to set some register values.
When compiling the design I get the following typw of warning on these parameters:
Warning (10230): Verilog HDL assignment warning at <design>.v(<line number>): truncated value with size xx to match size of target (yy)
If I use localparam instead, I get no warnings. Thus, the problem with the warnings are probably related to the HDL parameters tab in component editor.
In HDL parameters tab I can choose between several types for my parameters: string, integer, boolean, std_logic, logic vector, natural, or positiv. If I try to change the parameter type, the component editor hangs, and I have to close it. Also there is no description of what these types are..
I would not like to change my paramters to localparam since I would like to be able to oveeride them when simulating the system.
So, how do i fix the problem with these warnings.
