Filed:

May 8, 1998

Appl. No.:

09/074844

Inventors:

John Emery Nordman - Rochester MN

Assignee:

International Business Machines Corporation - Armonk NY

International Classification:

H03M 900

US Classification:

341100, 341101

Abstract:

An apparatus and method for improving the communication capabilities of computer systems is disclosed. The most preferred embodiments of the present invention use a series of data buffers and data registers to process an incoming high speed data signal. By using the buffers and registers, the incoming signal can be reformatted and manipulated at a much lower frequency than the original transmission frequency. The deserializer of the present invention also samples a greater portion of the incoming data signal than usual to further increase reliability. These various features of the invention provide for a more stable and reliable communication link and will also provide a less expensive solution for serialization/deserialization. The present invention includes a serializer that receives parallel data input from a computer and serializes the data for transmission over a high-speed serial communication link. On the receiving end, the present invention provides a deserializer that can quickly and efficiently transform the serial data back into parallel form for use within the computer system on the receiving end.

Abstract:

A method to validate data used in a design of a semiconductor product. The method includes (a) reading resources of an application set defining the semiconductor product in a partially fabricated state comprising fabrication layers up to and including a lowest conductive layer (b) reading a user specification that (i) is developed based upon the application set at the partially fabricated state and (ii) establishes at least one upper conductive layer added to the application set that completes the design of the semiconductor product, (c) allocating a new resource from the user specification to the design of the semiconductor product, said new resource having multiple parameters, (d) validating the allocation of the new resource against the resources of the application set and (e) propagating the allocation of the new resource and the parameters throughout a description of the semiconductor product.

Assignee:

LSI Corporation - Milpitas CA

International Classification:

G06F 17/50

US Classification:

716 3

Abstract:

During the design of semiconductor products which incorporates a user specification and an application set, the application set being a partially manufactured semiconductor platform and its resources, a template engine is disclosed which uses a simplified computer language having a character whereby data used in commands identified by the character need only be input once, either by a user or by files, and that data, after it has been verified to be correct, is automatically allocated to one or more templates used to generate shells for the specification of a final semiconductor product. Data must be correct and compatible with other data before it can be used within the template engine and the generated shells; indeed the template engine cooperates with a plurality of rules and directives to verify the correctness of the data. The template engine may generate one or more of the following shells: an RTL shell, a documentation shell, a timing analysis shell, a synthesis shell, a manufacturing test shell, and/or a floorplan shell.

International Classification:

US Classification:

716 1, 716 5, 716 18

Abstract:

A method, system, and a computer program product to provide correct and complete input into a shell generation tool that provides the infrastructure for design and development of an integrated circuit. Given a definition of a platform, in part a partially manufactured semiconductor product having some diffused and some configurable resources, a user can enter data that is correct and complete into the shell generation tool using several techniques. The tool itself can present data for the user to select that is complete and correct, i. e. , the data, inter alia, has no syntactic or other errors of an HDL, satisfies the constraints and naming conventions required by the tool, a customer of the semiconductor product, and/or the entity designing the product, provides appropriate timing and voltage levels, and is otherwise compatible with other data in the generation tool. If a user inputs data into an entry field, the tool automatically validates the input data by invoking one or more algorithms to determine its correctness and completeness before entering the data for shell generation.
