CPC G06F 30/3323 (2020.01) [G06F 30/337 (2020.01); G06F 30/367 (2020.01)] | 20 Claims |
1. A design support device comprising:
operation reception circuitry to receive an operation from a user;
program creation circuitry to create a ladder program in accordance with the operation received by the operation reception circuitry;
circuit block extraction circuitry to determine whether or not a configuration of a circuit block has been finalized under a condition that the circuit block is formed by detecting that one end of a circuit including a plurality of program elements of the circuit block is connected to one of two power rails included in the ladder program and that another end of the circuit is connected to another one of the two power rails, and extract the circuit block from the ladder program when it is determined that the configuration of the circuit block has been finalized;
a circuit block storage to store configuration information representing the configuration of the circuit block extracted by the circuit block extraction circuitry; and
notification circuitry to notify the user of the circuit block represented by the configuration information stored in the circuit block storage, as a candidate for a circuit block to be inserted into the ladder program.
