Box 301 -- Loveland, Colorado 80537 -- USA -- -- October 1990 -- Hello BSDL Parser Requestor, -- -- This Electronic Mail reply contains the computer specifications for -- Hewlett-Packard's Version 0.0 BSDL parser. This section of the reply -- explains the contents of the rest of this file. -- -- This file is composed of seven (7) parts: -- -- 1) How to use this file -- -- 2) UNIX* Lex source (lexicographical tokenizing rules) -- -- 3) UNIX* Yacc source (BNF-like syntax description) -- -- 4) A sample main program to recognize BSDL. -- -- 5) A BSDL description of the Texas Instruments 74bct8374 that is -- recognized by the parser, for testing purposes. -- -- 6) The VHDL package STD_1149_1_1990 needed by this parser. -- -- 7) [added 901016] Porting experiences to other systems. -- -- -- RECOMMENDATION: Save a copy of this file in archival storage before -- processing it via the instructions below. This will -- allow you to recover from errors, and allow you to -- compare subsequently released data for changes. -- -- DISCLAIMERS: -- -- 1. The IEEE 1149.1 Working Group has not endorsed BSDL Version 0.0 and -- therefore no person may represent it as an IEEE standard or imply that -- a resulting IEEE standard will be identical to it. -- -- 2. The IEEE 1149.1 Working Group recognizes that BSDL Version 0.0 is a -- well-conceived initiative that is likely to excelerate the creation -- of tools that support the 1149.1 standard. As such, changes and -- enhancements will be carefully considered so as not to needlessly -- disrupt these development efforts. The overriding goal is the -- ultimate success of the 1149.1 standard. -- -- LEGAL NOTICES: -- -- Hewlett-Packard Company makes no warranty of any kind with regard to -- this information, including, but not limited to, the implied -- waranties of merchantability and fitness for a particular purpose. -- -- Hewlett-Packard Company shall not be liable for errors contained -- herein or direct, indirect, special, incidental, or consequential -- damages in connection with the furnishing, performance, or use of -- this material. -- -- -- *UNIX is a trademark of AT&T in the USA and other countries. -- -- STD_1149_1_1990 VHDL Package and Package Body in support of -- BSDL Version 0.0 -- -- package STD_1149_1_1990 is -- Created 900525 package STD_1149_1_1994 is -- Give pin mapping declarations attribute PIN_MAP : string;
