Technical Field
The present invention relates to the field of computers, and more particularly, to a method for automatically correcting chip design codes and an application thereof.
Background
With the continuous development and progress of chip performance requirements and production technologies, the scale of chips is larger and larger, and the complexity of chip design is higher and higher. It is therefore necessary to check the chip code with a syntax checking tool before the chip code is delivered for chip verification. The first is that the workload of the verification personnel can be greatly reduced, and the second is that some problems which are difficult to be found in the chip verification stage can be found in advance by using a grammar checking tool.
Using a syntax checking tool, the code designer can be informed which potential problems the code has. However, the syntax checking tool has a disadvantage in that a huge number of warnings and errors are included in the log of the check because the chip code is large in scale. For errors, the designer must correct, and for warnings, the code designer may not be aware.

Detailed Description
The following detailed description of the present invention is provided in conjunction with the accompanying drawings, but it should be understood that the scope of the present invention is not limited to the specific embodiments.
Throughout the specification and claims, unless explicitly stated otherwise, the word "comprise", or variations such as "comprises" or "comprising", will be understood to imply the inclusion of a stated element or component but not the exclusion of any other element or component.
The technical solutions provided by the embodiments of the present invention are described in detail below with reference to the accompanying drawings.
Example 1
Referring to fig. 1, a method for automatically correcting a chip design code according to an embodiment of the present invention is described, which includes the following steps.
In step S101, an error code at the time of a chip design code syntax error or warning is acquired.
And checking the chip design codes through a grammar checking tool, and when errors or warnings exist in the grammars of the chip design codes, generating corresponding error or warning checking logs for the chip design codes. After the audit log is generated, the script captures the following information: the error code, the row of the wrong chip design code and the specific content of the wrong chip design code. And storing the error codes in a database so that when the errors occur again later, the error codes are automatically corrected according to the matching of the error codes and the corresponding automatic correction method. In the present embodiment, an excel document is created as the database for recording the syntax checking error code and the corresponding automatic correction method.
In step S102, matching is performed in the database based on the error code.
And searching whether the same error codes exist in the database, if the same error codes exist and the corresponding automatic correction methods exist, indicating that the errors or the warnings exist, adding the corresponding correction methods into the database by designers, and correcting the chip design codes of the errors or the warnings according to the corresponding correction methods in the database.
When there is no identical error code in the database, meaning that the error or warning is the first occurrence, an error code is added to the database and the error code and the wrong chip design code content are recorded in the audit log. Therefore, chip designers are reminded to add corresponding chip correction methods in the database. The next time the same error code is encountered, the corresponding correction method may be automatically invoked.
In step S103, a corresponding auto-correction method is called according to the error code to correct the chip design code.
And when the same error codes exist in the database, correcting the wrong chip design codes according to the specific contents of the wrong chip design codes and a corresponding automatic correction method, and generating corrected chip design codes to replace the original wrong chip design codes.
And recording the corrected chip design code into an inspection log for a chip designer to check. At this time, the chip designer only needs to know that the error has been corrected, and does not need to correct the error. If only one error exists in the chip design code, the energy saving is limited, but if a grammar checking tool checks a large number of errors and warnings, a chip designer can save a large amount of time for modifying the chip design code, and the chip development efficiency is greatly improved.
Taking [ WARNING ] B _1403: Flip-flop allocated not initiated, the error code of the alarm is B _ 1403. What is meant is that the trigger is assigned but not initialized. If a flip-flop is not initialized, it may represent an indeterminate state, i.e., it cannot be determined whether the output of the flip-flop is a 0 or a 1. Conversely, if a flip-flop is successfully initialized, the flip-flop can explicitly indicate whether the output is a 0 or a 1. If the output end of one trigger is in an indeterminate state, subsequent signal processing may be affected, so that the chip function fails and the expected function cannot be realized. For this reason, the chip designer needs to pay attention to the warning and make a modification to the code. The only way to process the alert is to initialize the trigger. Therefore, after the step of matching the error code is successful, a preset error correction method is called to correct the wrong chip design code.
In step S104, the error code is added to the database, and the error code and the chip design code are recorded in the inspection log.
And when the same error code does not exist in the database, adding the error code to the database, and recording the error code and the wrong chip design code content into the inspection log. Therefore, chip designers are reminded to add corresponding chip correction methods in the database. The next time the same error code is encountered, the corresponding correction method may be automatically invoked.
On the basis, more and more errors or warnings can be identified by the database, and most of errors or warnings encountered in chip design are covered finally, so that the aim of automatically correcting grammatical errors of chip design codes is fulfilled.
