Describes a driven clock signal.
Clock period in nanoseconds
Time in nanoseconds until first pulse.
Value of signal after first clock edge.
Duration in nanoseconds of first state in cycle.
Describes a driven one-shot signal.
Time in nanoseconds until start of one-shot.
Value of signal after first edge of one-shot.
Duration in nanoseconds of the one shot.
Specifies if a signal requires a driver. Default is false. The attribute driverType can further qualify what type of driver is required. Undefined behaviour if direction is not input or inout. Driver type any indicates that any unspecified type of driver must be connected
Describes a signal value. The signal value can be just a value (number), a strength, or both. If the "value" is not given, it should be considered an X (unknown). A weak strength with no value given is considered Z (tristate).
Describes a signal strength.
The value of a signal. 1 or 0 for single bit signals, unsigned numeric otherwise.
The strength of the signal. "strong" (default) or "weak".
