Method of generating development environment for developing system lsi and medium which stores program therefor

Abstract

A system LSI development environment generating method includes a compiler customizing section which generates a compiler from a configuration designation file, an assembler customizing section which generates an assembler, and a simulator generating section which generates a simulator. The configuration designation file contains a designation of hardware which executes instructions.

       45 . A method of generating a development environment for developing a system LSI, comprising: 
 analyzing an input command; and    in accordance with the analyzed command, generating a development environment of a system LSI on the basis of information of a configuration designation file in which a configuration of the system LSI is described,    wherein the development environment includes a verification vector generating section which generates a verification vector, and the verification vector generating section generates a verification vector of a processor from an operation instruction of the configuration designation file.    
   
   
       46 . The method according to  claim 45 , wherein the verification vector generating section generates ISA information from register information of the configuration designation file.  
   
   
       47 - 90 . (canceled)  
   
   
       91 . The method according to  claim 46 , wherein the ISA information includes information which is configured by a mnemonic, an operand list, and operand information.  
   
   
       92 . The method according to claim  47 , wherein the operand information includes operand type, bit width of an operand, and presence/absence of reference/substitution when the operand is a register.  
   
   
       93 . The method according to claim  48 , wherein the ISA information is used to generate a verification program.  
   
   
       94 . The method according to claim  48 , wherein the operand information is used to generate immediate data for inspection by using the information of the bit width when the operand is an immediate operand.  
   
   
       95 . The method according to claim  48 , wherein the operand information is used to generate a value which is set to a register when the operand is a register operand and a value of the register is referred.  
   
   
       96 . The method according to claim  51 , wherein the generated value is used to generate code data which is set to the register.  
   
   
       97 . The method according to claim  48 , wherein the operand information is used to generate code data for supplying to a log file when the operand is a register operand and a value is assigned to the register.  
   
   
       98 . The method according to claim  48 , wherein the operand information is acquired by analyzing the instruction behavioral description, the presence/absence of reference/substitution of the operand is acquired by the analyzing, when an operand is a register.  
   
   
       99 . The method according to claim  54 , wherein, when the operand is the register and a value of the register is referred, the value is generated at random within the range of a settable bit width.  
   
   
       100 . The method according to claim  55 , wherein, when the operand is the register and a value of the register is referred, the value is generated by obtaining a region which is set to an input.  
   
   
       101 . The method according to claim  56 , further including inspecting a boundary condition by generating points on and near the boundary of the region as input data.
