Module rapid placing and adjusting method

Abstract

The invention discloses a module rapid placement and adjustment method. The method comprises the steps of S1, obtaining input data; Wherein the input data comprises basic data of each storage unit aswell as interval height and interval width required to be spaced by each storage unit; Wherein the basic data of the storage unit comprises storage unit position coordinates, a storage unit height anda storage unit width; S2, obtaining the positions corresponding to the modules through calculation; And S3, according to the position information of the modules obtained through calculation, placingthe modules. According to the module rapid placement and adjustment method provided by the invention, the distance between the storage units can be rapidly adjusted, the adjustment speed of hundreds of storage units is within the second magnitude, the speed is greatly increased, and the iteration time of a project is reduced.

Description

technical field [0001] The invention belongs to the technical field of integrated circuits and relates to a method for quickly placing and adjusting modules. Background technique [0002] With the continuous development of the scale of integrated circuits, the scale of integrated circuits has grown from the initial scale of one million transistors to the current scale of billions of transistors. The storage units (memory) used in the design of integrated circuits have also developed from dozens of storage units at the beginning to thousands of storage units at present. Layout, as an important step in integrated circuit design, takes a lot of time, and placement of memory cells takes up most of the time. [0003] Due to its particularity, there are multiple pins that need to be connected on one side of the storage unit, which requires a specified distance between its placement and adjacent modules for pin winding. For the distance adjustment of the storage unit, it is necess...

Problems solved by technology

[0014] For the sake of simplicity, the above description is only for the placement of storage units of the same size. In real situations, the sizes of storage units are different, which greatly increases the complexity. For example, Figure 10

For irregular shapes (such as Figure 10 ), requires more steps to place and takes a lot of time
