Verilog 中一些低级内置门基元的 VHDL 等效项可以通过使用逻辑运算符如 NOT、AND、NAND、OR、NOR、XOR、XNOR 来实现。 下面是 Verilog 门基元的 VHDL 等效代码示例: or u1(x,y,z); in Verilog <=> x <=< span=""> y OR z; in VHDLand u2(i1,i2,i3); (Verilog) <=> i3 <=< span=""> i...

> typing has made a real difference in my work... at least an > improvement. I think Andy has it about right. If you think signed arithmetic was a tad messy in VHDL, wait until you find how successfully you can be screwed by Verilog. The really cool thing is that Verilog is...
How are Verilog and VHDL different from each other? Elaborate on the term HDL Simulators. What is the difference between == and === in Verilog? Tell me the five basic differences between Verilog’s task and function. What is Continuous Assignment? Explain how Verilog Repeat Loop works. Defin...
What is the difference between Verilog and VHDL? On the surface, not that much. Both are IEEE standards and are supported by all the major EDA vendors. Both can be used for designing ASICs and simulating systems. However, VHDL is altogether a grander language. Its support for system level...
The difference is that the simulator is gone and Modelsim is recommended. So for AHDL sims you have to first synthesize through Quartus and write out a VHDL/Verilog netlist for Modelsim(it's a structural netlist that you wouldn't even need to open, so you don't have to learn anything ...
We’ve been fans of the Yosys / Nextpnr open-source FPGA toolchain for a long while now, and like [Michael] we had no idea that theiross-cad-suiteinstallersets up everything so that you can write in Verilog or VHDL, your choice. Very cool!

difference is that carry lookahead adders are able to calculate the Carry bit before the Full Adder is done with its operation. This gives it an advantage over the Ripple Carry Adder because it is able to add two numbers together faster. The drawback is that it takes more logic. You will...
