Using a generate with for loop in verilog - Stack Overflow
stackoverflow.com

https://stackoverflow.com/questions/25924485/using-a-generate-with-for-loop-in-verilog

In the example without the generate, i should be a genvar not integer.Otherwise, both are valid depending on the version of the IEEE Std 1364 supported by your tool set. The generate construct was added in in IEEE Std 1364-2001 where the generate/endgenerate keywords are explicitly required. In IEEE Std 1364-2005 it became optional with the only requirement that if generate is used it must ...

https://www.einfochips.com/blog/system-verilog-assertions-simplified/

Nov 20, 2018 · Abstract. Assertion is a very powerful feature of System Verilog HVL (Hardware Verification Language). Nowadays it is widely adopted and used in most of the design verification projects.. This article explains the concurrent assertions syntaxes, simple examples of their usage and details of passing and failing scenarios along with waveform snippets for the ease of understanding.

A Verilog HDL function is the same as a task, with very little differences, like function cannot drive more than one output, can not contain delays. functions are defined in the module in which they are used.

First of all, Verilog cannot read images directly. To read the .bmp image on in Verilog, the image is required to be converted from the bitmap format to the hexadecimal format. Below is a Matlab example code to convert a bitmap image to a .hex file. The input image size is 768x512 and the image .hex file includes R, G, B data of the bitmap image.

Creating Finite State Machines in Verilog - Technical Articles

So a clever starting point is the state table. You’ll simply have to instruct Verilog what the machine is supposed to do at each state, not which gates or flip flops to use. An excellent construct for a state machine in Verilog is the Case statement. The body of each case should examine the state variable and its desired behavior.
