Timescale是SystemVerilog中一种用于控制时间单位和时间精度的机制。它定义了模块中时间尺度的默认取值,包括时间单位和时间精度。通过设置合适的timescale,可以确保模块中使用的时序相关操作按照预期进行。 在SystemVerilog中,timescale是在每个编译单元(module)中设置的,并且可以通过默认值继承特定层次结构下所包含子模块或实...
在SystemVerilog编程中,`timescale是一个用于定义时间单位和精度的关键字。它由两个部分组成:timeunit(时间单位)和timeprecision(时间精度)。默认情况下,编译器会设定一个全局的timescale,如使用VCS工具时,可能会设定为1ns的时间单位和10ps的精度。超出此精度的数值会进行四舍五入。在模块内部,开...
In SystemVerilog 1800-2012 spec Section 3.14.2.3, there is below content: " The time unit of the compilation-unit scope can only be set by a timeunit declaration, not a `timescale directive. If it is not specified, then the default time unit shall be used. "...
Verilog simulation depends on how time is defined because the simulator needs to know what a#1means in terms of time. The`timescalecompiler directive specifies the time unit and precision for the modules that follow it. Syntax `timescale<time_unit>/<time_precision>// Example`timescale1ns/1ps...
Although Verilog modules are expected to have a timescale defined before the module, simulators may insert a default timescale. The actual timescale that gets applied at any scope in a Verilog elaborated hierarchy can be printed using the system task$printtimescalewhich accepts the scope as an ...
