svf2loopsvf.h

在嵌入式系统中对Lattice CPLD软件升级时所需的VME文件生成所需源代码。将一个链上的不同厂家的CPLD产生的SVF文件转换成VME文件

/************************************************************************
*						SVF2LOOPSVF.H									*
*																		*
*	  This header file contains the module to compress an SVF file		*
*	  by constructing loops in the SVF.  If successful, it writes a		*
*	  temporary LOP file, which is similar to SVF but has the			*
*	  looping constructs.  The .LOP file will be converted into VME.	*
*	  If the looping is not successful, the partially created LOP file	*
*	  is removed and the original SVF will be converted into VME.		*
*                                                                       *
