inst

flat design下的instance

Parent Object

group, hInst, instTerm, io, pBlkg, ptn, rBlkg, sdp, topCell

Child Object

area,box,box_area,box_ll,box_llx,box_lly,box_size,box_sizex,box_sizey,box_ur,box_urx,box_ury,boxes,cell,group,hInst,instTerms,isAlwaysOn,isDontTouch,isHaloBlock,isIsolation,isJtagElem,isLevelShifter,isPhysOnly,isSpareGate,maskShift,name,orient,pHaloBot,pHaloBox,pHaloBox_area,pHaloBox_ll,pHaloBox_llx,pHaloBox_lly,pHaloBox_size,pHaloBox_sizex,pHaloBox_sizey,pHaloBox_ur,pHaloBox_urx,pHaloBox_ury,pHaloLeft,pHaloRight,pHaloTop,pStatus,pd,pgCellTerms,pgTermNets,props,pt,pt_x,pt_y,rHaloBotLayer,rHaloSideSize,rHaloTopLayer

hInst: inst的parent module

instTerms: instance的pin

pHalo*：placement halo相关的东西

pgCellTerms：cell的pg term

pgTermNets：cell pg term所连的net

rHalo*：route halo相关的东西

instTerm

instance的pin

Parent Object

hNet, inst, net

Child Object

cellTerm,hNet,inst,isInput,isOutput,isSpecial,isTieHi,isTieLo,layer,name,net,pd,pt,pt_x,pt_y

cellTerm: cell的term

hNet: 连接该inst term的hierarchical net，对图上红圈框住的net就是hNet,

           整条到top level的net就是net,是flatten的

io

io pad或者io pin的信息

Parent Object

fPlan
