binding a layout to schematic and putting pins in the layout

Inas,

A leaf instance simply means that this is not a hierarchical instance (on the schematic side, primarily). In other words, if you have a hierarchical design with an instance of a block called I1, you can't bind everything in that block in one go - you've got to go down to the individual components.

For binding one to many (e.g. m-factor) devices, you can either use:

bndAddInstsBindingByName(schCv "M1" layCv "I1")
bndAddInstsBindingByName(schCv "M1" layCv "I2")
bndAddInstsBindingByName(schCv "M1" layCv "I3")

etc. You may get warnings until you've bound enough instances. You can also use bndSetInstsBindingByName for the first call, but only the first for a particular schematic instance.

Or you could use bndSetObjectsBinding:

bndSetObjectsBinding(schInstId list(layInstId1 layInstId2 layInstId3))

i.e. you use the database id of the instances instead, and pass a list for the  layout side.

I can't really write your  pin placement code for you, sorry.

Regards,

Andrew.

Thanks Andrew for your answer.

About the pins placement, during my searching about how to place the pins, i found that once the schematic and layout becomes bounded the pins can be put easily on every instance in the layout depending on the connectivity, correct?

I just need you help on guiding me how to achieve that, please.

Thanks

I have no idea what you mean. Why would you want to put pins on every instance?

Ok 

I have written a sample skill script to bind between certain schematic and layout.

M7: is one multiplier.

M6: 4 multipliers

M9: 8 multipliers

This script worked fine with M7 and i can highlight it in the layout when selected in the schematic. But when it works on M6 it gives an error telling that there is no M6.5 in the layout.

From this error i deduced that i need to check for the value of idx after its incremented either it is equal to length of x or not. Can you please tell me how to do that?

I need to check if idx=length(x) if yes still inside the inner loop, if no, exit the inner loop and go to the outer loop. Can you tell me how to write this part in the script please?

Here it is:

procedure(bind_inst(schCV layCV instList)
let(( (idx 1) )
lxSetConnRef( "current_mirrors_skill" "CM_UPPER" layCV "CELLVIEW" ?schLib "current_mirrors_skill" ?schCell "CM_UPPER"
?schView schCV )
foreach(instName instList
     bndRemoveInstBindingByName(schCV instName)

        foreach(x setof(inst layCV->instances strncmp(inst->name instName 2) == 0)
                        bndAddInstsBindingByName(schCV instName layCV sprintf(nil "%s.%d" instName idx))
                            idx++
        )
     )
))

bind_inst(dbOpenCellViewByType("current_mirrors_skill" "CM_UPPER" "schematic_trial")
dbOpenCellViewByType("current_mirrors_skill" "CM_UPPER" "layout_skill3_xlclean") '("M7" "M6" "M9"))
