先编译,再仿真 -v指定库,verilog simulation lib会给的. 反标的方法就是:insert嵌入,做一个映射 map ,vcs -v 指定的min typ max,编译的时候加入这个特殊开关,就会按照这个最大最小延迟这种情况去跑,当然也可以编译的时候全部打开,仿真的时候再选定min max sdf如果很大的话,先sdf文件预编译,再用这个csdf这个加上

Hardness Analysis and Instrumentation of Verilog Gate Level Code for FPGA-based DesignsDependability analysis and test approaches are key steps in order to test and verify system robustness and fault-tolerance capabilities. Owing to the shrinking size of components, it is very difficult...
Verilog has built in primitives like gates, transmission gates, and switches to model gate level simulation. To see how the gate level simulation is done we will write the Verilog code that that we used for comparator circuit using primitive gates. module...

To design and simulate a 4:1 Multiplexer (MUX) using Verilog HDL in four different modeling styles—Gate-Level, Data Flow, Behavioral, and Structural—and to verify its functionality through a testbench using the Vivado 2023.1 simulation environment. The experiment aims to understand how different...
rst_n=1 and set_n=0 : one would expect q immediately changes states to 1, but based on the Verilog description, nothing will happen until the next "posedge clk." The reason is that when rst_n goes from 0 to 1, there is nothing triggering the execution of t...
Conventionally, an FPGA-based design is often described by hardware description language (HDL) such as Verilog or VHDL. The design is specified at register-transfer level (RTL) by registers and combinational logics between these registers. It is a low-level abstraction and designers must appropriat...
In the experimental result section, the Verilog code is applied to the FPGA, and modulation and demodulation results are given. In the conclusion section, the findings of this paper are highlighted and discoveries are pointed out. 1.2. Needs for reconfigurable modulation Communication systems are ...
Hi all, I have written some code for a basic and gate with a test bench, which works just fine when I run it in the RTL simulation, however whenever I try and run it in the Gate Level simulation I keep getting these error: Loading work.tb_and_4bit# ** Error: (vsim-19) Faile...
