// LPM Synthesizable Models (Support string type generic)
// These models are based on LPM version 220 (EIA-IS103 October 1998).
//------------------------------------------------------------------------
//
//-----------------------------------------------------------------------------
// Assumptions:
//
// 1. The default value for LPM_SVALUE, LPM_AVALUE, LPM_PVALUE, and
// LPM_STRENGTH is string UNUSED.
//
//-----------------------------------------------------------------------------
// Verilog Language Issues:
//
// Two dimensional ports are not supported. Modules with two dimensional
// ports are implemented as one dimensional signal of (LPM_SIZE * LPM_WIDTH)
// bits wide.
//
//-----------------------------------------------------------------------------
//START_MODULE_NAME------------------------------------------------------------
//
// Module Name : LPM_HINT_EVALUATION
//
// Description : Common function to grep the value of altera specific parameters
// within the lpm_hint parameter.
//
// Limitation : No error checking to check whether the content of the lpm_hint
// is valid or not.
//
// Results expected: If the target parameter found, return the value of the parameter.
// Otherwise, return empty string.
