A language cannot be just learn by reading a few tutorials.Its best learn when you try out new things.And for beginners I have written some basic as well as little bit advanced codes.Most of the posts have both the design and a testbench to verify the functionality of the design.Copy these codes and run them.Experiment with the codes and see how its working.Best Of Luck.
Just browse through some of the codes:
VHDL codes for common Combinational Circuits:
Some more codes are available here:
Resettable counter with testbench program
A programmable delay generator
BCD to 7-segement display decoder
Cyclic Reduntancy Check(CRC) Generator
Illustration of cloaked for loop by example
Usage of components in your design with example
Basic model for a FIFO Queue
Usage of "GENERIC" in VHDL using PISO example
Digital Clock in VHDL
Sine wave Generator
Function for division of unsigned numbers
Function for finding Square root of a number
Function for Matrix multiplication
Random number generator using PRSG
Keep checking this space for more example codes.If you think some thing is missing here request those examples here.I will try to work on your requests as soon as possible.
Some of the codes and testbench programs can be downloaded from here.
