Honored ContributorI have a design with an array of data as its generic:
entity XXX is generic (A : real_array(0 to 1); B : natural); ..... (real_array is a predefined data type of an array of real numbers) How do I pass the value of generic A in Modelsim command line? For example, I need A(0) = 0.0, A(1) = 30.0. I tried: (1) vsim -gA(0)=0.0 -gA(1)=30.0 (2) vsim -gA=(0.0,30.0) Neither works. Thank you for help!
Honored ContributorYou cannot set array generics from the command line - from the Modelsim Reference manual under the VSIM command:
"Limitation: In general, generics/parameters of composite type (arrays and records) cannot be set from the command line." So you're kind of stuck. Is there any reason you're setting them from command like and not just giving them a default value?Honored ContributorThank you for telling me,Tricky. I must admit I didn't read Modelsim Reference Manual carefully enough.:oops:
I want to pass the generic value just for the convenience to simulate several cases at one time. Anyway, I will find some workaround to do it.Honored ContributorIs the array always 2 elements? Could you not just have 2 separate real generics? you can force these from the command line.
Otherwise, I know its possible to use TCL to modify constants in a package. You could set up a TCL script to modify the constant then start modelsim simulation and batch up your tests this way. Unfortunately, I dont have the knowhow on this, but I've seen it done before.
