initial blocks where reg values are established instead of using a “reset” signal. ASIC synthesis tools don't support such a statement. The reason is that an FPGA's initial state is something that is downloaded into the memory tables of the FPGA. An ASIC is an actual hardware ...

5.Found pins functioning as undefined clocks and/or memory enables 原因:是你作为时钟的PIN没有约束信息.可以对相应的PIN做⼀下设定就⾏了. 主要是指你的某些管脚在电路当中起到了时钟管脚的作⽤,⽐如flip-flop的clk 管脚,⽽此管脚没有时钟约束,因此QuartusII把?clk?作为未定义的时钟.措施:如果clk...
这样设计指令集中就添加了addu,你就可以在MIPS代码中添加addu指令了,但注意指令条数不要超过32条,否则你要增大一下存储器memory.sv的容量。对了,你的“.bat”是指“.dat”吧? 2023-06-30· 安徽 回复1 鸿禧 Snivellus Snape 嗯嗯我试试谢谢博主 2023-07-01· 山东 回复喜欢 Dainel笑给你看...

I was trying to write a verilog code for a memory module which has has a bidirectional inout port for the data. But I also want to output high impedance during write or if MEM_OE(output enable) is not set. But my code as below cannot simulate the reading...
This will override all procedural assignments to a variable and is deactivated by using the same signal withdeassign. The value of the variable will remain same until the variable gets a new value through a procedural or procedural continuous assignment. The LHS of anassignstatement cannot be a ...
