Dear all,
I try to creat the vias in my own PDK, so i goes to technology file manger to creat cdsvias.
After that i return back to Virtuoso layout editting, to press "O", it shows NO CONTACTS/VIAS defined in constraint group.
I check the "Help", I should go to window>>contraint group manger for my vias defination, but i did not find this option in there.
Do you have any idea to sovle this problem, let me get the required VIAS in the contraint group.
Hi,
I have a bounding box of the parallel area between to layers of metal, and i want to create a skill method to fill that area with as many vias as possible.
this is my first attempt to write a skill program, but it seems like a basic operation every skill programmer probably implemented, so before i sit down to wrestle with it i was wondering maybe someone already have an implementation of it to share ?
Thanks for your time.
when lpp=list("prBoundary" "boundary") ?
I mean, what's the cellView~>prBoundary supposed to do?
Thank you.
Hi Andrew,
I had a question, which is not related to the topic.
I was trying to extract name of instance from layout XL, and every instnace has a " | " in starting eg. "|M1". Now when i was trying to save the name as inst~>name, it saves as " "|M1" ", i.e with quotation. Is there a way to convert this string to symbol. i need just |M1.
i had a case where the inst name was " "|M1.1" " also.

Hi All,
I am trying to export a series of nested parametric sweeps in Cadence. Using ocnPrint, the data is separated into sections according to the values of the outer sweep variables, but I would like to have a "flattened" output, where each sweep vector is in an adjacent column, rather than in a new subsection.
for example it is currently doing:
VTD_n = -3.000e-01
VTD_p -3.000e-01 0.000e+00 3.000e-01
0.0000e+00 9.9708e-01 9.9638e-01 9.9400e-01
1.0000e-02 9.9638e-01 9.9548e-01 9.9235e-01
2.0000e-02 9.9561e-01 9.9448e-01 9.9042e-01
.....
VTD_n = 0.000e+00
VTD_p -3.000e-01 0.000e+00 3.000e-01
0.0000e+00 1.0000e+00 1.0000e+00 1.0000e+00
1.0000e-02 1.0000e+00 1.0000e+00 9.9999e-01
2.0000e-02 1.0000e+00 1.0000e+00 9.9999e-01
and I would like it to do:
VTD_n -3.000e-01 -3.000e-01 -3.000e-01 0.000e+00 0.000e+00 0.000e+00
VTD_p -3.000e-01 0.000e+00 3.000e-01 -3.000e-01 0.000e+00 3.000e-01
0.0000e+00 1.0000e+00 1.0000e+00 1.0000e+00 1.0000e+00 1.0000e+00 9.9999e-01
1.0000e-02 1.0000e+00 1.0000e+00 9.9999e-01 1.0000e+00 1.0000e+00 9.9999e-01
2.0000e-02 1.0000e+00 1.0000e+00 9.9999e-01 1.0000e+00 1.0000e+00 9.9999e-01
Hi,
I am trying to use ocnYvsY function in the Outputs Setup in ADEXL(IC6.1.5-64b500.11) as ocean expression. What I am trying to do is I have current and swing expressions and I want to plot Swing vs Current after sweeping some other parameters. I know how to sweep variable from VIVAX but it is not efficient.
I tried some thing below but it didn't work
ocnYvsYplot(?exprx VCO_swing ?expry VCO_current) in Outputs Setup in ADEXL( VCO_swing and VCO_current are other expressions in Outputs Setup).
I have also tried "?wave" option also but it didn't work.
Could you help me how to do this?
Thanks,
yayla
I'm trying to use the code from this Cadence Solution ID: 20024536
; creating modgen group member list
d_cacheId = ciCacheGet( t_schLibName t_schCellName "layout" )
ld_instIds = d_cvLay~>instances
l_constMembers = nil
foreach( d_id ld_instIds
if( d_id~>pin == nil then
l_constMembers = cons( list( d_id~>name 'inst ) l_constMembers ) ) ; if
) ; foreach
; modgen constraint
d_constr = ciConCreate( d_cacheId 'modgen ?members ciExpandMembers( l_constMembers )
?params list( list( "numRows" 2 ) list( "numCols" 4 )
list("pattern" "custom ((A A A A) (B B B B)) ((R0 R90 R0 R90) (R0 MY R0 MY))") ) )
After this, I've added this line to auto-generate the modgen layout:
mgGen( d_cvLay d_constr )
The constraint and modgen are indeed getting generated, but the modgen is incomplete - It's created as two rows and four columns as mentioned in the constraint, but the pattern is not followed.
After this if I open the pattern editor manually and click apply, the modgen gets modified to the correct pattern - which means whatever constraint that is created is correct, but somehow the generated modgen group is incorrect.
Please help.
Thanks,
Leo
Hi,
I want to get a list of pins names and which direction the pins have from a symbol/schematic. I guess SKILL is the way to go? I new to SKILL, so if someone could push me in the right direction I would be grateful:)
I am currently writing an application where you can build/modify forms using graphics in Virtuoso. This is based on work Alex Wong did in 4.2.1. The problem I am having is displaying the labels in a font that resembles the font found on the forms.
Is there a way to specify a label to use an X font other than those supplied with the software?

How does assoc command of skill work ?
After looking closely into several numerical examples, I got the following findings:
a = '( ( 20n xx xx) ( 40n yy yy) (50n zz zz) ) assoc( 2e-08 a) returns: (2e-08 xx xx) assoc( 4e-08 a) returns: (4e-08 yy yy) assoc( 5e-08 a) returns: nil ß ?????but if I try:
a = '( ( 20e-09 xx xx) ( 40e-09 yy yy) (50e-09 zz zz) ) assoc( 2e-08 a) returns: (2e-08 xx xx) assoc( 4e-08 a) returns: (4e-08 yy yy)assoc( 5e-08 a) returns: (5e-08 zz zz)
I suspect that there is a numerical bug here. It looks like 5e-08 ≠ 50n . I noticed that for 20n,40n,80n,160n (power of 2) the problem doesn't appear.

Hi,
I frequently need to select objects within an area defined by a donut. Didn't find a way of doing this as all the commands I found seem to work with a quare boundry box. Any suggestion?

Are there equivalents of these functions in IC615? I have some custom code which was developed in IC5 that uses these functions to get information like via width/height/rows/columns, etc.
Thanks

Hi All,
I am getting below error in CIW while opening virtuoso XL. And then XL not opening. My version is 615. Could you please let me know the reason for this?

Hi,
I want to modify the orientation of a rod Object keeping its bBox unchanged. Is there any function such as dbsetq for rod objects? using which i can tranform the properties of rod.

Hello,
I would like to sort list of instances created by
instList = setof(inst cv->instances inst->cellName == "cnf_digi")
result is
"|column_digi(1)|cnf_digi"
"|column_digi(0)|cnf_digi"
"|column_digi(15)|cnf_digi"
"|column_digi(14)|cnf_digi"
"|column_digi(13)|cnf_digi"
"|column_digi(12)|cnf_digi"
"|column_digi(11)|cnf_digi"
"|column_digi(10)|cnf_digi"
"|column_digi(9)|cnf_digi"
"|column_digi(8)|cnf_digi"
"|column_digi(7)|cnf_digi"
"|column_digi(6)|cnf_digi"
"|column_digi(5)|cnf_digi"
"|column_digi(4)|cnf_digi"
"|column_digi(3)|cnf_digi"
"|column_digi(2)|cnf_digi"
I tried used
(sort instList lambda (A B)(alphalessp (A->name)(B->name))))
But result is
"|column_digi(1)|cnf_digi""|column_digi(10)|cnf_digi"
"|column_digi(11)|cnf_digi"
"|column_digi(12)|cnf_digi"
"|column_digi(13)|cnf_digi"
"|column_digi(14)|cnf_digi"
"|column_digi(15)|cnf_digi"
"|column_digi(2)|cnf_digi"
"|column_digi(3)|cnf_digi"
"|column_digi(4)|cnf_digi"
"|column_digi(5)|cnf_digi"
"|column_digi(6)|cnf_digi"
"|column_digi(7)|cnf_digi"
"|column_digi(8)|cnf_digi"
"|column_digi(9)|cnf_digi"
alphalessp doesn't know sort integer in string as lessp. Is there any possibilities how to sort list of instances according to their names without complicated parsing string to integer and use lessp command?
Thank you very much for answer in advance.

Hi,
Can we have a variable with rexMatchp?
My requirement is as below:
a = "m_1"
b = '("m_1" "m_1_1" "m_1_2")
c = setof(i b !rexMatchp("_[1-9]*$" i) // This will return nil.
My desired output for c is "m_1" and at the same time, I want to exclude a_[1-9] where a="m_1"
Could you please guide? Is it possible with rexMatchp?
Thanks,
Ram
Where do I find the library manager bindkeys?
