// IEEE1800-2017 Clause 22.7 // This directive specifies the time unit and time precision of the design // elements that follow it. The time unit is the unit of measurement for time // values such as the simulation time and delay values. // The `timescale compiler directive specifies the default unit of measurement // for time and delay values and the degree of accuracy for delays in all // design elements that follow this directive, and that do not have timeunit // and timeprecision constructs specified within the design element, until // another `timescale compiler directive is read. // The integers in these arguments specify an order of magnitude for the size // of the value; the valid integers are 1, 10, and 100. // The character strings represent units of measurement; the valid character // strings are s, ms, us, ns, ps, and fs. `timescale 1 s / 10 ms `timescale 10 us / 100 ns `timescale 100 ps / 100 fs // This file should be emitted from the preprocessor unchanged.
