addCell function example

Here is an example that puts the elements written in a list, into the open (empty or no) schematic. addCell('("gnd" "vdc" "vdd" "noConn" "vbit" "vpulse" "vsin")). The library names can be specified with the fifth parameter list. addCell('("gnd" "noConn") t nil t '("analogLib" "basic"))

Personnal comment : this function is given for 'howto' puspose, i do not really use it generally. I prefer function array2sch, see below.

freeLCK function example

When a schematic view is opened in Read mode. Remove existing lock that belongs to you (that you have the right to delete). Opened from a crashed session for instance. And it puts the schematic in the edit mode.

array2sch function example

Take, or generate for your needs, a list with the cellName and its input and output incremanted (or not) names. Then is creates an array of cells with net and labels on top in the opened schematic cellView. See array2sch_tuto.il example file.

schematic2symbol function example

From an open schematic with pins, generate a rectangle symbol with the pins at the same location distance of the schematic. For practical simplicity, i use named label to put pins in a nearby area.

vdcGen function example

From an open schematic, generates an array or a list of analogLib vdc with shifted verilog syntax bit, in order to use the parameter in a simulation (ADE, ADEXL, or whatever new maestro tool).

menu function example

Add a menu in CIW ( former icfb ), the pull down menus with the function i generally use.

rexFindCell function example

search in the libraries defined in the cds.lib where exist a pattern

rexFindCell("or" "CORELIB" t) ;<== search in the library CORELIB where there an 'or' with case insensitivity.

rexFindCell("^mos" ) ;<== search everywhere a cell starting with 'mos'

;=>(("ahdlLib" "mos_tft") ("ahdlLib" "mos_level1"));<== answer

whereIncludeCell function example

When i don't remember where i have used a cell in my design, i search with : 'whereIncludeCell'. (Warning a bit long to search in all the libraries.

whereIncludeCell( "ampli");<= search in all libs where i put my_amplifier or so.

;=> (("functional" "libContents" "amplifier") ... ("my_lib" "simu_mem_2cell" "hold_amplifier")) ;<= answer

whereIncludeCell( "inv_cor" "CORELIB");<== search where inv_core is used in the CORELIB

;=> (("CORELIB" "JKS3" "inv_core") ...) ;<== answers (...too many lines to print for this example)

prettyPrint function example

print the postscript of the viewing cell, and convert it on the go with ghostscript, with a slightly wider pen size (setlinewidth=5 instead of 1). In order to havec better contrast of the lines.

__VV__ See below an example of generated image view. Normally it's the best definition you could get for a presentation or a technical document. __VV__

updateCellviews function example

When a copy was done without checking by mistake the button "[] Update Instances: Of new copies Only", or when a collegue send you a library but some cells are defined from another library, but a copy is present in the current library. Then this script goes and search if a cell is defined in the current cell and affect it to the instance (technically, its the master of the instance that is updated).

In the example, the buffer is not present in the library, so it cannot be updated. This function works also for Layout : updateCellviewsL(). But in Layout, there is a predefined function : Tools->remaster_Instances that does the job allready.

mos2fet function example

update a schematic with all the symbol to be modified. Could be looped easily on the entire library. Update net position except if the net does not touch the center of the pin.

⭐ Could be used to translate a design to another techno. ⭐

See mos2fet_tuto.il example file. The cell 'buffer_HM...' does not exist in the library, an so, is not updated.

c35toc18('(("nd02d2" "my_nd02d2" "PICMIC1_ksabra"))) ;<= replace nd02d2 for fcking Duplicate declaration with v2lvs/cdl not permiting hierarchycal naming lib1_cellSameName lib2_cellSameName LVS MATCH

genBox function example

From the core schematic level, it takes the pins in the existing cellview and generate a template file for the padRing function, and execute this template. It means that it generates schematic, symbol and layout pad rings with conner abuted with the default value. The template permits to adapt the size, and the space of the diod cells. This is functionnal off-the-shelf with AMS035 and IBM130 by default. Should be adapted with other technos. (change spacing metal name, IO lib names etc.) pinName list order start from bottom left and are posed one by one in the counter clockwise order. Here is another example. The parameter xn specifies the number of pad in X row. [omited=> square]. The first two optional number are for X and Y spacing between pads. It is usable if spacer cells exist with multiple size. A long time ago, i used to create a pCell spacer, so that i could stretch the spacer easily, but i gave up. procedure(createPadRing( l_pins @optional (spaceL 5) (spaceH 5) (libname getEditRep()~>libName) (cellname getEditRep()~>cellName) @rest rest)

generateAllPins function example

When placing the instance manually in a layout, i generally don't want to place the pins manually. So the script loop on the pins of the schematic, and created the layout pin rectangle and label where the should be on the layout instance.

createInstPinsch function example

Take a list of instance and put wire with label on it, but change names of wanted pinName.

image2layers.py function example

That is a python script that generate pixels reactangles.

The script will take the more frequence color of the input image and for every pixel create a skill command to crerate that rectange. Then finaly merge all the layers. Use it preferably on a bmp 4-bit depth color image (reduce to possible 16 RGB color) Will generate DRC errors to be waived for sure. But you can insert your favourite logo or a tribute to a dear colleague.

shell> python3 ~/Skill/image2layers.py  #<= echo help script
shell> python ~/Skill/image2layers.py image.png 1 0.065 0.065 > image.il  
virtuoso> load("image.il")

image2layers.il function example

image2layers("~/groupU/Mi2i/pics/wharol2.bmp" 1) ;<= execute image2layers.py and generate the image into the current cellview

---

rectangleLabel2pin.il function example

Generate pins on top of rectangles with theire label

emacs_ipcPipe.il function example

When clicking one menu->emacs_ipcPipe, it creates a named pipe in /tmp/ipcPipe2CAT_$USER Then a line in emacs in skillMode can be executed in virtuoso with a shortcut bindkey (C-c-f or C-c-v). The outputed result from virtuoso can be pasted back into emacs with bindkey C-c-s. Possibly, it can be used by another external script.

echo -e '1+1' >  ~/.emacs2icfb.il
echo 'loadEOF' > /tmp/ipcPipe2CAT_ebecheto 

🍎 VERY VERY VERY HANDY 🍎

⭐ STAR ⭐ I could not code anymore without this feature. I came-up with this solution inspired by gnuplot-mode.

- if you read until here you probably learnt something.
