Problems solved by technology
The traditional method is to manually adjust the design of the search engine, the design of the physical storage, and the connection between the search engine and the physical storage based on the latest design requirements. Usually, the connection between the search engine and the physical storage is relatively small. Complex, manual adjustment methods make the final RTL design code update cycle long and error-prone

The invention discloses a method and device for designing dynamic entries in an Ethernet chip. The method includes establishing a two-dimensional matrix encoding table representing the connection relationship between the search engine and the physical memory and the depth of the physical memory; A script program that parses the codelist and automatically generates the RTL design code. The invention expresses the relationship between the search engine and the physical memory by establishing a two-dimensional matrix coding table, and uses script programs to analyze the two-dimensional matrix coding table to automatically generate RTL design codes, thereby improving the design efficiency and accuracy of dynamic table items.
Description
technical field [0001] The invention relates to the technical field of chip design, in particular to a method and device for designing dynamic table items in an Ethernet chip. Background technique [0002] In the design of Ethernet switching chips, the design of dynamic shared table entries is one of the core technologies, which achieves a reasonable balance between flexible and dynamic management of table entries and minimization of physical area. Before the final tape-out of the switching chip, the RTL (RegisterTransfer Level, register transfer level) code design scheme may change with the demand, making the connection relationship between the search engine and the physical memory change frequently, and the search engine may also be increased or decreased at the same time , may also increase or decrease the physical memory, and may also change the depth of the physical memory, which brings many uncertainties to the RLT code design and verification. The traditional method ...
