Abstract

A license contract of ASIC development tool is completed between an ASIC vendor and a tool vendor, and then the ASIC vendor makes a sublicense contract of the tool with a customer who intends to develop an ASIC. Information including a customer name, a development tool name, a lease condition of the development tool, a request for license key lease is transmitted from the customer computer 11 to the ASIC vendor computer 10. Receiving the information, the ASIC vendor computer 10 transmits to the tool vendor computer 12 information of requesting the license key lease if it is determined that the predetermined condition of license key lease is satisfied. In response to the receipt of the information, the tool vendor computer 12 transmits a license key through the ASIC vendor computer 10 to the customer computer 11.

Claims

1. A license management method, wherein an ASIC vendor computer, a tool vendor computer, and a customer computer are interconnected through a network, the method comprising the steps of:

(a) the customer computer transmitting first information to the ASIC vendor computer, the first information including a customer name, a development tool name, a lease condition of the development tool, and a request for a license key lease;

(b) in response to reception of the first information, the ASIC vendor computer checking whether the first information satisfies a predetermined condition of the license key lease, and transmitting to the tool vendor computer second information of requesting for the license key lease if it is determined the predetermined condition is satisfied; and

(c) in response to reception of the second information, the tool vendor computer issuing a license key for the customer.

2. The license management method according to claim 1, wherein the lease condition in the step (a) includes a period of the license key lease and number of the development tools.

3. The license management method according to claim 1,

wherein the predetermined condition in the step (b) is part of a sublicense contract completed between the ASIC vendor and the customer in advance,

wherein a license contract to permit the sublicense contract has been completed between the tool vendor and the ASIC vendor before the sublicense contract is completed.

4. The license management method according to claim 3,

wherein a storage device storing an accounting database is coupled to the ASIC vendor computer, and paid amount information including a paid amount of each customer is recorded in the accounting database,

wherein in the step (b), the ASIC vendor computer calculates a license key lease fee based on the first information received from the customer computer,

wherein the predetermined condition includes that the paid amount of the customer is more than or equal to the license key lease fee.

5. The license management method according to claim 3,

wherein a storage device storing a license management database is coupled to the ASIC vendor computer,

wherein in the step (b), the ASIC vendor computer records at least part of the received first information into the license management database, and the second information includes at least part of a record in the license management database.

6. The license management method according to claim 3, further comprising the step of:

(d) in response to third information on a request for an integrated circuit mass production from the customer, the ASIC vendor computer transmitting fourth information on startup of the integrated circuit mass production to the tool vendor computer.

7. The license management method according to claim 6, wherein, in the step (d), the customer computer transmits the third information to the ASIC vendor computer.

8. The license management method according to claim 7,

wherein a storage device storing an accounting database is coupled to the ASIC vendor computer, paid amount information including a paid amount of each customer and a unit price of product fee are recorded in the accounting database,

wherein in the step (d), the ASIC vendor computer:

calculates a product fee based on the third information and the unit price of product fee;

judges whether the paid amount of the customer is more than or equal to the product fee before the transmission of the fourth information to the tool vendor computer; and

performs the transmission of the fourth information if the judgment result is affirmative, or else, transmits to the customer computer fifth information indicating that the integrated circuit mass production is impossible.

9. A computer program product comprising a computer program for causing an ASIC vendor computer to perform a license management, the computer program causes the ASIC vendor computer to perform the steps of:

(a) in response to receipt of first information of a customer name, a development tool name, a lease condition of development tool, and a request for a license key lease from a customer computer, checking whether a predetermined condition of the license key lease is satisfied; and

(b) if it is determined that the predetermined condition is satisfied, transmitting second information of the request for the license key lease of the development tool to a tool vendor computer.

10. The computer program product according to claim 9,

wherein the computer program causes the ASIC vendor computer in the step (a) to calculate a license key lease fee based on both the first information and an accounting database recording paid amount information including a paid amount of each customer,

wherein the predetermined condition is that the paid amount of the customer is more than or equal to the license key lease fee.

11. The computer program product according to claim 10,

wherein the computer program causes the ASIC vendor computer in the step (a) to record at least part of the received first information into a license management database,

wherein in the step (b), the second information includes at least part of a record in the license management database.

12. The computer program product according to claim 11, wherein the computer program causes the ASIC vendor computer to further perform the step of:

(c) in response to third information on a request for an integrated circuit mass production from the customer, transmitting fourth information on startup of the integrated circuit mass production to the tool vendor computer.

13. The computer program product according to claim 12,

wherein a unit price of product fee is further included in the accounting database,

wherein the computer program causes the ASIC vendor computer in the step (c) to:

calculate a product fee based on the third information and the unit price of product fee;

judge whether the paid amount of the customer is more than or equal to the product fee before the transmission of the fourth information to the tool vendor computer; and

perform the transmission of the fourth information if the judgment result is affirmative, or else, transmit to the customer computer fifth information indicating that the integrated circuit mass production is impossible.

14. A license management apparatus comprising:

an ASIC vendor computer;

a storage device coupled to the ASIC vendor computer; and

a computer program stored on the storage device for causing the ASIC vendor computer to perform a license management,

wherein the computer program causes the ASIC vendor computer to perform the steps of;

(a) in response to receipt of first information of a customer name, a development tool name, a lease condition of development tool, and a request for a license key lease from a customer computer, checking whether a predetermined condition of the license key lease is satisfied; and

(b) if it is determined that the predetermined condition is satisfied, transmitting second information of the request for the license key lease of the development tool to a tool vendor computer.

15. The license management apparatus according to claim 14,

wherein the computer program causes the ASIC vendor computer in the step (a) to calculate a license key lease fee based on both the first information and an accounting database recording paid amount information including a paid amount of each customer,

wherein the predetermined condition is that the paid amount of the customer is more than or equal to the license key lease fee.

16. The license management apparatus according to claim 15,

wherein the computer program causes the ASIC vendor computer in the step (a) to record at least part of the received first information into a license management database,

wherein in the step (b), the second information includes at least part of a record in the license management database.

17. The license management apparatus according to claim 16, wherein the computer program causes the ASIC vendor computer to further perform the step of:
