However there was one caveat. Here's the format I used to instant Generate Statement - VHDL Example. Generate statements are used to accomplish one of two goals: Replicating Logic in VHDL; Turning on/off blocks of logic in VHDL; The generate keyword is always used in a combinational process or logic block. It should not be driven with a clock.

generic(일반화)이란 Entity 내에 기술하며 generic 의 매개변수를 entity에 전달 함으로서, and VHDL is used to describe hardware (parallel execution). This inherent di erence should necessarily encourage you to re-think how you write your VHDL code. Attempts to write VHDL code with a high-level language style generally result in code that nobody understands. Moreover, the tools used to synthesize2 this type of code have a tendency to -generic is the right switch but you may need to use colons not dots. From the docs: irun -generic "vlog_top:vhdl_inst1:gen => 4" top_level_design_unit . So for you: irun -generic 'tb.G_WAVEFORM_TYPE => "yyy"' I've also encountered a lot of problems using generic packages with Modelsim, because the syntax is quiet complex and not very understandable documented in the "Designers Guide to VHDL 2008" which is the only book I know about the 08 features :/ But the upper solution works with Modelsim.

如下代码将MUX实例化两次，其中的数据类型分别为4bit std_logic和2bit std_logic。.

exportable) subprograms, constants, and types are declared, and a "package body", in which the subprogram implementations are defined, along with any internally-used constants and types. Yeah, VHDL sucks like that. You can't pass in generic sized 2-D arrays, for instance. You can have a generic array of fixed width vectors though.

There are several ways to handle this. You can give the generic a default value like this: generic(DataWidth : integer := 8); If you don’t assign anything to this generic when instantiating the module, the default value is chosen.

VHDL Generic. In VHDL, generics are a local form of constant which can be assigned a value when we instantiate a component. As generics have a limited scope, we can call the same VHDL component multiple times and assign different values to the generic. We can use generics to configure the behaviour of a component on the fly. Generic is a basic and very useful function of the VHDL. It allows creating more flexible and easy to modify components. Proper use of it will save your time and make your code clearer and more readable.

Generic associations are provided via the module instance parameter value list. List the values .
