The next step would be, to be also flexible in how many bits are multiplexed at once. So let's introduce a generic BITS to specify the data bits. VHDL has a problem to define array of unconstrained arrays (this is solved with VHDL-2008, but not all vendors support this feature). So solution 2 uses a flat vector to pass all bits to the mux. Vhdl and verilog implementation of clock 20 and 50 and 10 and 30 Mhz generation. Fpga implemantaion of clock generation. If i am working on 50 mhz clock generation i want to design clk counter with some clk 10mhz geneartion then what can i do for that one to implemneting 20mhz from 50mhz without using any ip core directly using coding tecniques we can imp.

increases (4-little bit if 16 advices, 6-little bit if 64, etc.). I'michael currently making use of custom sorts as insight, but this can make making the code more generic problematic.With function.typearrays containing of:
Does anyone have a solution/idea to create it generic? I wish to use this mux for 256.16-little bit solutions and maybe actually 1024.24-bit as nicely. Composing the whole factor by hands can't become the VHDL method to do it.
The choice is allowing a power generator write the codé, but l'd like tó avoid that if feasible.

Presently there are usually 4 methods to a soIve this:
Remedy 1:
You can specify a set width STDLOGICVECTOR (SLV), which can end up being used to construct some other vectors (let's contact them STDL0GICVECTORVECTORs (SLVV).
Now you can specify your organization as comes after:
The inner reasoning can be reduced tó:
This cán end up being enhanced by removing
tointeger(unsignéd(.))
into á functionality known as toindex.Answer 2:
The following phase would be, to become also versatile in how numerous bits are usually multiplexed at once. So allow's introduce a common Pieces to specify the information bits. VHDL offers a issue to specify selection of unconstrained arrays (this is certainly resolved with VHDL-2008, but not all suppliers help this function).
So option 2 utilizes a smooth vector to pass all pieces to thé mux.
Alternative 3:
Getting flexible in Slots and Pieces can furthermore be done by using a genuine 2-dimensional variety -gt; STDL0GICMATRIX (SLM).
This wouId be the organization announcement:
You could furthermore write a generate cycle to do some wiring or you can specify some features to perform thát.
And tháts the matching architecture:
Option 4:
If your device facilitates VHDL-2008 and arrays of unconstrained vectors, then you can make use of this kind:
Type Conversion:
The following images shows all probable type conversions relating to: SL, SLV, SLVV ánd SLM.

lf you are curious in even more, I could add my comprehensive collection of vector, véctor-vector and mátrix forms, functions and methods. Please give me a sign.
Edit:
Here can be the bundle PoC.typical.vectors. It'h included in my PicoBlaze Collection which is currently in beta state. The launch of PoC can be also planned, but not so developed. Therefore I integrated some necessary deals and modules into this library. The source code license is 'Apache License 2.0'.
