Fig. 1 is a schematic flow chart of the method for automatically generating a watermark on an IP according to the present invention.
The implementation, functional features and advantages of the objects of the present invention will be further explained with reference to the accompanying drawings.
Detailed Description
It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The invention is further described below with reference to the accompanying drawings.
The invention provides a method for automatically generating a watermark on an IP (Internet protocol), which comprises the following steps as shown in figure 1:
and S1, judging whether the target IP opens the writable right.
And integrating the written program into a program list of a right mouse button in advance by using a function HICreateSimpleMenu () (for creating a simple menu function), so that the program is ready to be run later. And opening a target IP to be watermarked, clicking a right mouse button, finding the program to be clicked and run, and capturing the authority mode of the IP environment by the program to judge whether the target IP can be written or not. Specifically, the target IP runs the program through layout view (layout interface).
S2, if the target IP has opened the writable right, the step S3 is entered; and if the target IP does not start the writable right, popping up a warning, and returning to the step S1. The warning includes: and prompting a user to start the writable permission of the target IP.
And if the target IP does not start the writable right, executing a show _ warning _ form () subprogram, popping up a warning dialog box, and prompting a user to start the writable right. The Show _ warning _ form () subroutine is implemented by the function hidisplayappbox () (create and display dialog window function). And when the user opens the target IP writable right, repeating the step S1.
S3, reading the IP process information of the target IP; and reading pre-stored watermark hierarchy list information.
The IP process information includes process library hierarchy information of the target IP, process information used by the target IP, and Foundry information corresponding to the process used.
Reading the IP process information of the target IP comprises the following steps: if the target IP has opened the writable permission, capturing a Process File (Process technology File) of the target IP by a function techngettefile () (a Process File information capturing function), namely IP Process information; meanwhile, the current time point is obtained through a function currenttime () (displaying the current time function), and a time format required when the target IP is finally watermarked is obtained through format conversion.
The watermark hierarchy list information comprises a plurality of foundation information which are prestored and process information used by each foundation. The fountain information is generally information corresponding to a mainstream agent factory in the technical field at present, and watermark hierarchical list information is generated from the information of all mainstream agent factories and stored.
And S4, matching the watermark hierarchy list information with the IP process information to obtain watermark hierarchy information required by a preset fountain in the watermark hierarchy list information.
Specifically, the matching the watermark hierarchical list information and the IP process information includes: and matching the fountain information in the watermark hierarchy list information with the fountain information corresponding to the process used by the target IP, and extracting the watermark hierarchy information corresponding to the matched fountain information.
S5, reading the IP name (IP name) of the target IP, and making the watermark layer information and the IP name into the IP watermark label of the target IP. And then, generating an IP watermark module by the IP watermark label, and placing the IP watermark module on a newly-built mark layer of the target IP. Finally, an IP watermarking module is placed at the coordinates (1, 1) of the mark layer.
The IP name includes Vendor information, Project Num information, and Version information.
Specifically, a function dbCreateLael () (create tag function) is used for creating a watermark tag in a format required by a target IP or a foundry, then a lemakeCell () (create sub-module function) is used for generating all formatted watermark tags in a mark layer of ViewType (graphic interface format), and a module IP watermark module is created.
And then, a function dbCreateInst () (a prototype function is created) is used for placing the established IP watermark module at the position of the coordinates (1, 1).
