Hi,

I am trying to use "sed -e 's " from SKILL code to edit unix file "FileA", to replace 3 words in the 2nd line.

How to run below multiple commands using  ipcBeginProcess, Should I use ipcWait or ipcCloseProcess ?

Using && to combine , will that work as I have to work serially on each command. ?

With below code only the first command gets executed. Please advise.

FileA="/user/tmp/text1.txt"

sprintf(Command1 "sed -e '2s/%s/%s/g' %s > %s" comment1 get(form concat("dComment" RDWn))->value FileA FileA)
cid = ipcBeginProcess(Command1)


sprintf(Command2 "sed -e '2s/%s/%s/g' %s > %s"  Time getCurrentTime() FileA FileA)
cid1 = ipcBeginProcess(Command2)


sprintf(Command3 "sed -e '2s/%s/%s/g' %s > %s"  comment2 get(form concat("Duser" RDWn))->value FileA FileA)
cid2 = ipcBeginProcess(Command3)

Thanks,

Ajay

Hello,

I am in a need of a skill program to find all instances of a specific cell (Including Mosaics), throughout the hierarchy. The program should print the instance's name, xy coordinates at the top level, and extract a label name that is dropped on top of it. In case there is no label on top of the found instance, the program should print "No Label Found" in the report text file. This program aims to map PADs cells within top level.

I am using the below Cadence's solution to find instances and it works well. The missing feature is to identify LABELs that are on top of the found instances. 

I tried to use dbGetOverlap() function, within the below code, in few setups but it seems to fail to identify the existence of labels on top of the found instances.

For example: 

overlapLabel=dbGetTrueOverlaps(cv cadr(instBox) list("M1" "text"))

I am interested to add to the Cadence's solution below some code in order to identify labels on top of the found instances.

Any tip would be greatly appreciated.

Thanks,

Danny

Hi,

I want to convert ircx file(which is from TSMC,inclued EM Information) to ict or emDataFile for Voltus-fi.

I tried many way, but I can not make it. Can anyone give me some advice?

and I  do not installed QRC.

below is some tools installed my server. 

IC617-64b.500.21 is used.

Hello,

I have created an appForm with  the following attachmentList and size:

?attachmentList list(hicLeftPositionSet | hicRightPositionSet ; field 1
                     hicLeftPositionSet | hicRightPositionSet ; field 2
etc.

?initialSize    800:800
?minSize        800:800
?maxSize       1600:800

If I reduce the minimum y-size (?minSize        800:200), scrollbars are not inserted, unless I remove the attachmentList constraints.

Is it possible to have both scrollbars and "hicLeftPositionSet | hicRightPositionSet"? 

Thank you,

Best regards,

Aldo

I can get the bound stdcells using bndGetBoundObjects, but not get what each individual stdcell corresponds in layout.

Is there a way to get the layout bound stdcells of an array schematic symbol if the layout stdcell name do or do not match the symbol naming?

Once the schematic array stdcells are bound to the layout stdcells, how to get the correct terminal term~>name and net~>name?

Example of a schematic symbol and layout stdcell:

Schematic

INV<0:2>    instTerms~>terms~>name = ("vss" "vdd" "A" "Y")

                   instTerms~>net~>name = ("<*3>vss" "<*3>vdd" "in<0:2>" "nand2A,nand3B,nor2B")

Layout ( I know it is bad practice, but it happens )

stdcell1 instTerms~>terms~>name = ("vss" "vdd" "A" "Y")

             instTerms~>net~>name = ("vss" "vdd" "in<0>" "nand2A")

I23        instTerms~>terms~>name = ("vss" "vdd" "A" "Y")

             instTerms~>net~>name = ("vss" "vdd" "in<1>" "nand3B")

INV(2) instTerms~>terms~>name = ("vss" "vdd" "A" "Y")

             instTerms~>net~>name = ("vss" "vdd" "in<2>" "nor2B")

Inside the scope of isCallable there is code which I don't want to be executed.

The procedure named in isCallable to-day is callable.

I want to make that procedure so it cannot be called.  How do I do that?

I can't change the isCallable line or the scope.  I want to change its behavior by making sure that the procedure does not exist (obviously this would be done before the code is executed).

I have a SKILL script that executes the callback of a menu item, and depends on first redefining an environment variable. 

When a user interrupts the script with ctrl-C, the script cannot finish to set the environment variable back to its default value.

How can I write the script in a way that handles a user interrupt to reset the changed environment variable after the interrupt?

Hi,

I am running simulation in ADEXL and need a custom function for VIVA to apply same procedure to all signals saved in output. For instance, I have clock nets and I want to get all of them and look at the duty-cycle, edge rate etc.

It is a little more involved than about part since I have some regex and setof to filter before processing but if I can get all signals for current history, I can postprocess them later.

In ocean, I am just doing outputs() and getting all saved signals but I was able to do this in VIVA calculator due to the difficulties in getting current history, test name and opening result directory

thanks

I have a modeless informational dialog box defined at the beginning of a SKILL script, but its contents don't display until the script finishes.

How do you get a modeless dialog box contents to display while a SKILL script is running?

procedure(myproc()

   prog((myvars)

     hiDisplayAppDBox()    ; opens blank dialog box - no dboxText contents show until script completes!

     ....rest of SKILL code in script...launches child processes

   );prog

);proc

When I place a pcell and do not change the W parameter (default is used) the value is not saved in the OA cell property.

When I change the default value of the super master now, the old pcell will get the new default value automatically because there is nothing saved inside the OA cell for this parameter.

Do you have any Idea, that how we can save the default values in the OA cell properties so that this value doesn't get updated if the default values are updated in the new PDKs

Can anybody assist with a Skill code /function to disable all callbacks

Howdy,

            In the netlist generated after parasitic extraction, nodes have been added at fracture points to add parasitic devices. For example, in the image below, I'm referring to the nodes IN#1 and IN#2. Is there a way to determine their co-ordinates relative to the layout co-ordinate system? I could not find them in the Skill command reference and when I query the parasitic elements in the extracted view, it gives the graphical pin locations of the elements rather than the physical.

Thanks

Hello,

After deleting cells using the following loop:

foreach(cellId ddGetObj(libName)~>cells
    ddDeleteObj(cellId)
)

the following warnings are printed in the CIW:

*WARNING* (SCH-2162): "... symbol" has been updated since "... schematic" was last saved. Validate that the schematic is correct and run Check and Save to suppress this warning.
*WARNING* (DB-270337): dbGetInstHeaderMaster: Failed to open cellview '...' from library '...' in read-only mode because the cellview does not exist. This cellview was instantiated in cellview '...' of library '...'. Ensure that the cellview exists in the library.

Is it possible to turn them off?

Thank you

I'm trying to generate IBIS models for the parts that I'm designing.  I'm designing using CADENCE Virtuoso.

Hi, I want to add values to components in my SiP design such as 1nF or 15nH. There is already in existence a COMP_VALUE property reserved for this as shown during BOM generation. This property is not visible under the Edit/Properties dialog for component or symbol find filters. We have already created user properties called COMP_MFG and COMP_MFG_PN that it editable at a component level. When we try to add COMP_VALUE it is reported as a reserved name in Cadence but this name is not listed in the properties dialog. Is there a way to turn on the visibility and editablility of this or other hidden reserved Cadence property names? How can I assign a string value to the COMP_VALUE property?

Thanks

I use "Degassing" function in APD. It provides the options "Even Layers" and "Odd Layers". 

My first question is that is there any additional setting to choose the specific layer? 

The second question is that  is there any way to select a range to place degassing hoe? I don't want to place holes at the whole layer.

Thanks!  

Iam new to Package design SIP tool.

I had created the DIE package using SIP. Kindly give the direction how to map the created DIE package in Allegro pcb editor 17.2 ver.

In Allegro design capture CIS tool we had created the schematics file. The DIE which we are using is having 100pins, We had created the DIE in SIP tool. Out of 100 Die pins, only 90 pins is getting connected others are NC pins. We had mapped the Bond fingers only for 90 Die pins in the SIP package. But in the Schematics we had created the DIE logic symbol for 100 pins. Please advice whether we can able to import the DIE package in the allegro tool. In this scenario while importing the 100 pin DIE package in allegro pcb editor will the net connectivity will be shown from the DIE pad to Bond fingers and from Bond fingers to respective components? Please suggest whether we are going in the right path or please advice what we have to proceed with.

Thanks in Advance,

Rajesh

I have created a die and other components as symbols in sip and placed the symbols in sip through logic import capture netlist. It shows net connectivity but i couldn't add bond finger from the die pins. Please help on this.
