Title: Creation of Smith Chart by OCEAN in Cadence ViVA
Post by cheap_salary on Dec 12^th, 2016, 4:53am

I can easily create Smith Chart by OCEAN for Cadence Wavescan and Cadence AWD.

However I can not create Smith Chart by OCEAN for Cadence ViVA.

The followings are both uneffective in Cadence ViVA.

Code:

displayMode("smith")
awvSetSmithModeType( window(2) "impedance" ?subwindow 3 )

How to create Smith Chart by OCEAN in Cadence ViVA ?

Self-follow-up.

I can create Imedance Chart by using following code in Cadence ViVA.

Code:

wid = newWindow()
displayMode("smith")
awvSetSmithModeType(wid, "impedance", ?subwindow 1)

If you prefer admittance chart, use following.

Code:

wid = newWindow()
displayMode("smith")
awvSetSmithModeType(wid, "admittance", ?subwindow 1)

We have to use both displayMode() and awvSetSmithModeType() in this order for Cadence ViVA.
This procedure is different from Cadence Wavescan and Cadence AWD.

You also can use the public (but not properly documented, for some reason) smithType("impedance") function which is more OCEAN-like.

I've requested that it is properly documented.

Note that the procedure is slightly different with the Qt-based ViVA in IC615 onwards because the new implementation doesn't support a window being able to morph from a rectangular to a circular window type - you have to create the window the way you want it up front, rather than changing it later.

Andrew.

This can work as sams as "awvSetSmithModeType(wid, "impedance", ?subwindow 1)".

There is no cool method to create new smith chart by Skill Codes.

So I have to invoke either code of the followings.

Code:

wid = newWindow()
displayMode("smith")
awvSetSmithModeType(wid, "impedance", ?subwindow 1)

Code:

wid = newWindow()
displayMode("smith")
smithType("impedance")

You could just do this:

Code:

procedure(MySmithChart(@optional (type "impedance"))
prog1( ; this returns the return value of the first argument
newWindow()
displayMode("smith")
smithType(type)
)
)

Then you can do:

wid1=MySmithChart()
wid2=MySmithChart("admittance")

The benefit of a programming language is that you can write functions to make things simpler (and cooler, to use your phrase).

Andrew.

Actually my code is a part of large procedure.

Anyway skill functions are incomplete for Smith Chart.
For example, I can not place marker on Smith Chart by Skill.

You should contact http://support.cadence.com and request that as an enhancement.
