Re: How to calculate the metal area for some power signals

That sounds like the single-layer form of Net Area Ratio to me. (Documented in the SVRF manual, svrf_ur.pdf.)  Does this work for you, or is there something not quite right?

 

If you need something a bit more customized, there might be some code you can leverage from the Solutions for Physical Verification manual, particularly the examples using DFM.  Look for calbr_solns_pv_user.pdf in your mgcdocs directory.

Thnaks Robert.

What about if i want to show nothing instead 0? If i enter nothing in my Access table why DxDatabook fill the field with 0? 0 is not nothing. This happen only for field marked as "Show Unit for IEC62"

Same for us, too. We use IEC62 format and have symbols that are used in mutiple parts database entries. Some parts have a value and some not. A visible "0" at the parts with no value is not nice.

It is a limitation of how real numbers are handled as far as I understand the problem.

Can I run an executable or batch file at startup?

$

Currently when I want to open DxDesigner, I run a exectuable (of batch file) that copies some files from a network drive to my local drive and then invokes viewdraw.exe. For a couple of reasons, it would make more sense to just run a batchfile or executable via the Run at Startup option in DX. Unfourtunally this doesn't work, DX complains about the .bat or .exe extension not being registered.

 

How should I get this to work?

 

Thank you in advance!

COVER FREE AREA

  Hi,

I merged 5 different gds files into a unique layout like the image for example

 

layout example.jpg

I would like to know if it's possible to cover all free area around chips with a specific layer, using a command like "create polygon" or something like this on tcl script running calibredrv

 

Many thanks in advance

 

   Best Regards

Hello Robert,

 

Where would I find this info within the project, checked settings, nothing like this there.  I am having the same problem, pcb: Error 5709: Could not open schematic Schematic1.

 

Thanks

Need some help, using PADS VX1.2, trying to compile my schematic and getting this error.

 

Already tried the symbol library fix, and that didn't seem to work.

 

Here is the full error list,

Re: COVER FREE AREA

Hi Luciano,

That's very doable. I've drawn large chip-surrounding polygons required by foundries before in just such a fashion. Here's some code that will do the trick. This would be typed into the terminal from which you launched your CalibreDRV session at the DRV TCL prompt.

 

set cwb [ find objects -class cwbWorkBench ]

set L [ $cwb cget -_layout ]

$L create polygon TOPCELL 0 0 0 2u 2u

 

CalibreDRV uses object-oriented TCL, which you don't run into everywhere. Let's break the code down:

  1. The first line grabs the calibreWorkBench object from which all layout objects are born.
  2. The second line spawns a layout object from the cwbWorkBench object. Once we have that, we can start drawing. Oh, that last argument that looks so funny, that's "hyphen-underscore-'layout'" typed in there.
  3. The third line does the job, drawing a poly across a 2um X 2um area. The arguments are examples. More generally, the command looks like "$L create polygon <cellName> <layer> <x0 y0> <x1 y1> [x2 y2] [x3 y3] ...
    1. cellName := The name of the cell in which you want to draw the polygon.
    2. layer := The GDS layer number on which to draw the polygon. If your layer has a non-zero datatype, represent it like a float: layer 5 datatype 3 would be 5.3.
    3. x0 y0 := First polygon vertex.
    4. x1 y1 := Second polygon vertex. If you only provide 2, DRV will assume you are providing the lower left and upper right corners of a rectangle.
    5. xn yn := Additional vertices for more complicated polygons.

Re: Simulation of edge to tri-state transition

Hello Kjell,

Currently we can't simulate this case in HyperLynx. In IBIS there is no support for simulating drive to 3-state or 3-state to drive modes.  Additional V-t tables in the IBIS model are needed to know how to transition to/from 3-state to driving high or low. It is not too difficult to generate this data, the problem is that IBIS does not have a place to have it. The simulator also needs to have transitions implemented between the 3-state and driven modes.

 

This is a good idea and I encourage you to post it to our HyperLynx Ideas site:

The problem with odb++ is the pin map,

In odb++ file,

# CMP 1

CMP 85 11.8799213 -5.1072834 180 N U423 TPS7A8300RGRR ;0=1,1=0.0394

TOP 0 11.9478347 -5.1466535 180 N 132 6 U423-1

TOP 1 11.9478347 -5.1269684 180 N 0 1552 U423-2

while import into Hyperlynx, it recognize as component U423,  pin as U423-1 instead of U423 pin 1. Although I can use text edit to delete U423-, but it is not an ideal solution.

I'm having this exact same problem. Behavior is the same whether I invoke from toolbar icon or from menu Tools\Package.

Please advise.

It is probably caused by the spaces in the names of the project file and path. Try replacing these to see if the issue is resolved.

Thanks Robert,

 

Tried this already, didn't work.  Also, I have many projects with spaces in the project and path and have never not had them compile.  I have read mentor software doesn't like that but it has never been an issue for me.

Thanks Robert,

 

I was referring to how to  view this information,

SECTION DesignInfo

LIST IndependentLibraries

VALUE "DIR [W] . (PSDB)"

 

I downloaded crimson editor and was able to verify the information above.
