In reply to ssubramaniam: The short answer is the BNF syntax does not allow it. A task only allows a subset of constructs within it, and always is not part of that set. There is no need for the always construct in SystemVerilog. always block_of_statements; could be written as initia...
An always block is one of the procedural blocks in Verilog. Statements inside an always block are executed sequentially. Syntax always @ (event) [statement] always @ (event) begin [multiple statements] end The always block is executed at some particular event. The event is defined by a sensi...
wire), while the left-hand-side of a procedural assignment (in an always block) must be avariabletype (e.g., reg). These types (wire vs. reg) have nothing to do with what hardware is synthesized, and is just syntax left over from Verilog's use as a hardwaresimulationlanguage...
SystemVerilog adds several new syntax in addition to the Verilog always block, primarily to address the exceptions noted above. You can read more about these constructs in my articleSystemVerilog always_comb, always_ff. Conclusion Verilog always block is one of the four procedural statements in th...
naming in a sensitivity list. The redundancy served no appreciable purpose and users will gladly adopt the more concise and abbreviated @* syntax. · Clear intent- an always @* procedural block informs the code-reviewer that this block is intended to ...
‘browse-up’ approaches to administering systems, which proves that common practice isn’t always good practice. In such scenarios, an end user device used by an administrator can be one of the easiest paths into the target system, even if access is via a 'bastion host2' or ‘jump box...

Synthesis honors the mixed blocking and non-blocking assignments, although the Verilog Language Specification no longer supports this construct. Synthesis generates a syntax error for detection of mixed blocking and non-blocking assignments within an ALWAYS block. 5.4.8. Confine SystemVerilog Features...
