Is Verilog concurrent or sequential?
I understand all initial blocks start at time 0. But are these initial blocks then executed sequentially i.e. if a initial block has more than one lines, will all of them executed sequentially or concurrently.
In which order do the blocking assignment statements are executed in a sequential block?
Statements are executed sequentially in each block and both blocks finish at time 0ns. To be more specific, variable a gets assigned first, followed by the display statement which is then followed by all other statements.
What is the problem with IF statement in VHDL?
Using an if statement without an else clause in a “combinational process” can result in latches being inferred, unless all signals driven by the process are given unconditional default assignments.
How is a sequential block executed in Verilog?
If a timing control statement appears within a block, then the next statement will be executed after that delay. The sequential block shall be delimited by the keywords begin and end.
How are parallel blocks executed in javatpoint Verilog?
If a timing control statement appears within a block, then the next statement will be executed after that delay. The sequential block shall be delimited by the keywords begin and end. All statements in the parallel blocks are executed at the same time or concurrently.
How are the statements in a parallel block executed?
All statements in the parallel blocks are executed at the same time or concurrently. It means that the next statement’s execution will not be delayed even if the previous statement contains a timing control statement.
When to use the Join construct in Verilog?
To make the contents in concurrent, fork..join construct is used. For example: Refer to Verilog Procedural Blocks, Concurrent and Sequential Statements sites for further information. All of the initial, always, and continuous assign statements in your design execute concurrently starting at time 0.
