Abstract
A method and a system for recording an integrated circuit version are provided. The method is adapted to a register in an integrated circuit, which includes the following steps: recording the integrated circuit version with N bits, in which N is an integer greater than 1; and amending only a bit value of at least one bit selected from the N bits that have not been used for denoting any past integrated circuit version each time when the integrated circuit is revised.
Claims4
A method for recording an integrated circuit version, which is adapted to a register in an integrated circuit, the method comprising:
- recording the integrated circuit version with N bits, wherein a bit value of each of the N bits is initialized to a first value, the first value is 0 or 1, and N is an integer that is greater than 1;
- and
- amending only one or more of the bit values that are still the first value among the N bits each time when the integrated circuit is revised.
A system for recording an integrated circuit version, comprising:
- a register arranged in an integrated circuit, which is configured to record the integrated circuit version with N bits, wherein a bit value of each of the N bits is initialized to a first value, the first value is 0 or 1, and N is an integer that is greater than 1;
- and
- a control circuit coupled to the register, which is configured to amend only one or more of the bit values that are still the first value among the N bits each time when the integrated circuit is revised.
