Layer Filters

Layer Filters applied

Layer Filters – comfortable view

Layer Filters – full cycle

Layer Filter – layerprops

• Default path:~/.calibrewb_workspace/layerprops

• Can be replaced by environment variable:MGC_CWB_CONFIG_DIRS

setenv MGC_CWB_CONFIG_DIRS /path/to/calibre/CWB/

• Can be combined by several layerpros files inMGC_CWB_CONFIG_DIRS

setenv MGC_CWB_CONFIG_DIRS path/to/calibre/CWB/: ${PROJ_MGC_CWB_CONFIG}

DRC RVE Check Text Override File (CTO File)

• Allow you to specify highlight colors, display layers, document links, and other settings

• Example (DRC_RES.db.cto)

RR:RE:M3.S.13RVE Show Layers: METAL3 RVE Link: http://intranet.marvell.com/28nm/TN28CLDR002_1_3.pdf#page=153

rpt_basic.iniThe configuration file follows the generic INI file format.

It contains multiple sections which define the content of the HTML output.

Section names are enclosed in brackets, and the sections contain key/value pairs specified one per line:

; comment on section 1[section1]key1 = value1key2 = value2; comment on section 2[section2]key1 = value1key2 = value2

DRC HTML Report Database Map File• Syntax

– rdbFile, rdbType, layoutFile, layerPropertiesFile, layoutFileType

• Example (data_map.file)

– DRC_RES.db,,IO_TOP.gds,layerprops,– rdbType and layoutFileType - undefined

layerprops

• Use common layerprops for CalibreDRV
