Embodiment Construction

[0045] Such as figure 1 As shown, it is a block diagram of a dynamic labeling system for merging IP parameterization units in an embodiment of the present invention; a dynamic labeling system for merging IP parameterization units in an embodiment of the present invention includes: a label control unit 1 and a customer IP parameter table Build module 8.

[0046] Such as figure 2 Shown is the working flow chart of the label control unit of the embodiment of the present invention; the label control unit 1 is activated after the virtual image IP is generated, and the label control unit 1 includes a parameter mapping table generation module 2 and an IP label generation module 3 . Before the virtual image IP is generated, the label control unit 1 works in the background.

[0047] The parameter mapping table generation module 2 scans all the parameters of the IP parameterization unit to make a parameter mapping table 4, and compares the parameter mapping table 4 made with the para...

Abstract

The invention discloses a dynamic tag system for IP parameterization unit merging. The dynamic tag system comprises a tag control unit and a client IP parameter list establishing module. The tag control unit comprises a parameter mapping table generating module and an IP tag generating module. The parameter mapping table generating module scans all parameters of an IP parameterization unit to make a parameter mapping table, and compares the parameter mapping table with a former value; if the parameter mapping table is different from the former value, the IP tag generating module is called to generate an IP tag in real time, and the made parameter mapping table is stored to be used for next comparison; the client IP parameter list establishing module is used for scanning the IP tag and translating the IP tag to form a corresponding client IP parameter table. The invention further discloses an implementation method of a dynamic tag for IP parameterization unit merging. Automatic merging of variable IPs can be achieved, and therefore merging efficiency and accuracy can be improved.

Description

technical field [0001] The present invention relates to the field of semiconductor integrated circuit manufacturing, in particular to a dynamic labeling system for merging IP parameterized cells (Pcells); the present invention also relates to a dynamic labeling system for merging IP parameterized cells implementation method. Background technique [0002] In chip design and production, many parametric units need to be used. The parametric unit is essentially a computer script, which is generally written in the Skill language of Cadence, and its corresponding layout has passed the design rule check (DRC, design rule check) and Layout and schematic (LVS) verification. Under the condition of a given parameterized unit, the required unit layout structure can be obtained by inputting the corresponding parameters, which is convenient for designers to design the layout. [0003] The Component Description Format (CDF) library file is the property description file of the device, whi...
