4. Variable declarations in the static scope# 还是参考 IEEE Std 1800-20176.21Scope and lifetime 这一小节:Variables declared in a static task, function, or procedural block default to a static lifetime and a local scope. However, an explicit static keyword shall be required when an initializatio...
When used in conjunction with other variable types, use of the keyword var will be without effect for both simulation performance and synthesized circuits. Var can be used with enumerated types (covered in Chapter 4) as well as other built-in Verilog and SystemVerilog types. Sign in to ...
