Logic and latches

Function blocks in the group “Logic and latches”. Each link opens the block page; sorted by library and name.

Block Page title Library What it is for
AND AND Basic Digital Boxes Logical “AND” of two or more inputs.
bd49_singlealarmmemory Single alarm memory Basic Digital Boxes This block is dedicated to deal with alarm states.
bd50_alarm_memory Alarm memory Basic Digital Boxes The block is an alarm memory, with up to 16 alarms.
bd51_boolean_memory Boolean memory Basic Digital Boxes The block is a single-cycle signal delay block, or a boolean signal memory cell.
bd52_flipflop Flip-flop Basic Digital Boxes The block controls its output value based on inputs, which read rising or falling edge, and thus set or reset the output.
bd53_latchflipflopnode Latch flip-flop Basic Digital Boxes The block is a gate for logical signals.
bd56_singlealarmmemorydelay Single alarm memory with delay (v1.1) Basic Digital Boxes The block is an alarm memory which responds after a time delay only.
bd57_alarmmemoryext Extended alarm memory Basic Digital Boxes The block is an alarm memory with up to 16 alarm inputs.
F_TRIG F_TRIG Basic Digital Boxes The block detects a falling edge and generates a pulse on the output with duration of one cycle.
NEG NEG Basic Digital Boxes The function negates the input.
NOT NOT Basic Digital Boxes The function negates the input.
OR OR Basic Digital Boxes The function performs a logical OR of two or more inputs.
R_TRIG R_TRIG Basic Digital Boxes The block sends a pulse with duration of one cycle on the input signal's rising edge.
ROL ROL Basic Digital Boxes The function rotates the input vector to the left.
ROR ROR Basic Digital Boxes The function rotates the input vector to the right.
RS RS Basic Digital Boxes Classical RS Flip-Flop circuit.
SHL SHL Basic Digital Boxes The function moves the bit pattern from right to left.
SHR SHR Basic Digital Boxes The function moves the bit pattern from left to right.
SR SR Basic Digital Boxes The circuit acts as a classical RS flip-flop circuit.
Toggle Toggle Basic Digital Boxes Block works as a toggle switch, Input In reacts on raising edge, The first raising edge switches the output to TURE.
XOR XOR Basic Digital Boxes Function calculates the exclusive disjunction of two or more inputs.
