Method for managing design files shared by multiple users and system thereof

A non-transitory computer-readable medium storing computer-executable code for managing design files shared by multiple processes, the non-transitory computer-readable medium comprising:

• code for creating a lock table, wherein each entry of the lock table comprises information regarding which design file in a plurality of design files stored in a design library accessible to each of a plurality of computers is locked by which process, wherein the lock table is created in a process memory of a first process in a first computer in the plurality of computers when the information indicates that the design files in the design library are accessed only by the first process in the first computer;
• code for moving the lock table from the process memory of the first process to a common memory in the first computer in response to information indicating that one of the design files in the design library is to be locked by a second process of the first computer, the common memory accessible to both the first and second processes;
• and
• code for moving the lock table from a predetermined memory in the first computer to the design library in response to information indicating that one of the design files in the design library is to be locked by a process in a different computer in the plurality of computers.

A system for managing design files shared by multiple processes, the system comprising:

• a processor;
• and
• a memory storing a set of instructions which when execute by the processor configured the processor to:
• create a lock table, wherein each entry of the lock table comprises information regarding which design file of a plurality of design files stored in a design library accessible to each of a plurality of computers is locked by which process, wherein the lock table is created in a process memory of a first process in a first computer in the plurality of computers when the information indicates that the design files in the design library are accessed only by the first process in the first computer;
• move the lock table from the process memory of the first process to a common memory in the first computer in response to information indicating that one of the design files in the design library is to be locked by a second process of the first computer, the common memory accessible to both the first and second processes;
• and
• move the lock table from a predetermined memory in the first computer to the design library in response to information indicating that one of the design files in the design library is to be locked by a process in a different computer in the plurality of computers.
