Changes

A digital clock is a periodic pulse generator similar to the analog square wave generator. Many digital devices such as flip flops require a clock for their operation. From a clock's property dialog, you can change its default name and set its period as well as its pulse width. The pulse width is the duration of the high (1) portion of the signal in each period. The clock input itself must have a period of a certain duration in order for dynamic devices to operate properly. This minimum period is expressed in its inverted form as the maximum frequency of a digital device.

==Digital Bus Connectors==

You can edit the pin connections of bus connectors. By default, the wires coming into splitters and combiners are distributed automatically in the following manner. The wires connected to the top pin become the least significant bits of the splitter or combiner. The rest of the wires coming into the splitter or combiner are placed into the higher bits of the splitter or combiner. After the circuit state is updated, the splitter or combiner will display the bit numbers of the wires. The wire distribution can be customized by turning off the "Auto Distribute" checkbox in the bus connector's property dialog and entering the pin numbers manually. The first leg will use the wires in the first dialog box, etc. For example, if you have a 1-to-2 splitter, you can specify that you want bit 0 of the net to go onto the lower pin of the bus connector and bit 1 of the net to go to the upper pin. Multiple bits can be specified for each pin using colons and commas to group bits.
