赋值语句 在 Verilog 中,信号的赋值方式有: (1) 连续赋值(Continuous Assignment)语句 使用 assign 语句为 wire 类型的变量赋值,不可以对寄存器类型的变量赋值.例如: assign c=a&b; 或直接用: wire c=a&b; (2) 过程赋值语句(Procedural Assignment) 过程赋值语句又可以分为非阻塞赋值(Non-Blocking Assignment...
Concurrent signal assignments are concurrently active and re-evaluated when any signal on the right side of the assignment changes value. The re-evaluated result is assigned to the signal on the left-hand side. Supported types of concurrent signal assign
The VHDL equivalent for the latter is a "<=" signal assignment in concurrent code. --- Quote End --- What is mean of "continuous assignments"? Do you mean "unblocking assignment" in Verilog? And since local variable can be used outside process, even for pure combinatio...
Concurrent signal assignment Case statement Process statementsAnswer: C) Process statementsExplanation:Process statements define the sequential behavior of an architecture.Discuss this Question 31. Which of the following cannot be used as the name of the architecture in VHDL?
You cannot use if outside of the process because it is a sequential statment. The other way to do it is to use conditional assignment: use ieee.std_logic_misc.all; --for reduce function ... --later outside a process: error <= '0' when xor_reduce(ip) = '0' else '1'; --...
I implement the continuous transfer function of the second order low pass filter by VHDL. I don't know why my result are very strange. And I saw a lot of warning when I compile it. Do this wanning affect to my result? This is warning: --- Quote Start --- Warning (1413...
