Design diagrams to detect rising and falling edges and store Boolean values.

node_icon
Resets a channel using four global variables to handshake with the writer and reader State Machines of the channel.
node_icon
Counts down when the decrement input is true. This node is loaded with a value when the load input is true.
node_icon
Counts up when the increment is true. This node is reset when the reset input is true.
node_icon
Detects a transition from TRUE to FALSE on the input signal.
node_icon
Detects a transition from FALSE to TRUE on the input signal.
node_icon
Stores a value from input d when s is TRUE. When r is TRUE it resets output q to 0.
node_icon
The read state machine for a command construct.
node_icon
Stores information about the previous TRUE values of the signal. You can reset this node to search for another TRUE value of the same signal.
node_icon
The write state machine for a command construct.
node_icon
Toggles the Boolean state of the output.
