C_POC_NUL	ite ( ( SYNTHESIS_TOOL /= SYNTHESIS_TOOL_ALTERA_QUARTUS2 ) , NUL , '`' )	WORKAROUND: for Altera Quartus-II Version: 15.0 Issue: character 0 (NUL) causes Quartus-II to crash, if uses to pad STRINGs characters < 32 (control characters) are not supported in Quartus-II characters > 127 are not supported in VHDL files (strict ASCII files) character 255 craches ISE log window (created by 'CHARACTER'val(255)') Solution: PoC uses backtick "`" as a fill and termination symbol, if a Quartus-II synthesis environment is detected.
