I have defined my state as follows: type state_type is (s0, s1, s2, s3); signal state: state_type; Now I would like to use this state information to form another signal
I have a very simple FSM which should drive some output signals of an external RAM. The problem that I have comes with handling the data bus
I want to describe an entity that can either function normally or be put i开发者_StackOverflown a test mode. The general design I have is a top level entity that wraps the \"real\" entity and a test e
Inside a process I have something like this: CASE res IS WHEN \"00\" => Y <= A; WHEN \"01\" => Y <= A;
I\'ve been scratching my head since my first VHDL class and decided to post my question here. Given that 开发者_如何学运维I have a declared entity (and also an architecture of it) and want to instant
LLVM is very modular and allows you to fairly easily define new backends.However most of the documentation/tutorials on creating an LLVM backend focus on adding a new processor instruction set and reg
I\'m taking a university course to learn digital design using VHDL, and was doing some reading in the book the other day where I came across the following piece of code:
how much \"sound inputs\" of high fidelify (128K 44kH) may be made via ordinary FPGA (Xilinx Spartan 3, what-so-ever) without using external开发者_JAVA百科 ADC converters (only voltage-balanced input
I want to simulate a microprocessor designed using VHDL in ModelSim. I wanted to know what the output file format of the simulation is?
VHDL code First of all, sorry for the redirect, but it\'s easier that way. I\'m building a digital clock, but as you can see, clock_AN and clock_seg_out do not change. Is this caused b开发者_开发知识
