What Does Timescale 1Ns/1Ps Mean. Web `timescale 1ns/1ps means that all the delays that follow (like# 5.1234) are interpreted to be in nanoseconds and any fractions will be rounded to the nearest picosecond (5123ps). We usually use it during design of a digital circuit and verification

However, all delays are represented as integers. // this will give 0 ns delay!! Web what does timescale 1ns 1ps mean? Web the 'timescale specifies how time is managed in the verilog simulator. Web in the below code, timescale is `timescale 1ps / 1ps. So 1ns/100ps means that the time unit for the verilog code that follows has a time unit of 1ns with a resolution of 100ps. When you compile the files using your compiler, the compile order is as above (i.e. Web now, if we use timescale of 1ns/1ps, then the #1 delay denotes delay of 1ns and the minimum delay that we can give to an entity is 1ps (#0.001). You'll get a detailed solution from a subject matter expert that helps you learn core concepts. Means ur time scale is ns with resolution or least count of 1ps.
It contains 2 numbers, the time unit and the precision; Web this problem has been solved! We usually use it during design of a digital circuit and verification Here, 1ps/1ps = 1 = 10 0, as the result is 10 0, no digit will be taken after decimal. Web `timescale 1ns / 1ps // for carryout only check value for addition, we don't care what is carryout falg value for other operations! C.v defines module c and no timescale directive. Web verilog is a hdl hardware description language used to model electronic systems. Use the following timescale constructs to use different time units in. Web `timescale 10ns/1ns the time_unit is the measurement of delays and simulation time, while the time_precision specifies how delay values are rounded before being used in the simulation. Means ur time scale is ns with resolution or least count of 1ps. Defines module b and timescale 1ps/1ps at the very top of the file.
