Forum Post: RE: Confirm dialog problem before closing a form with 'X'
Thanks, eDave, I got the point. It is not concerned with axlCmdRegister(). If I add button named 'cancel' and only check the curField equal 'cancel', previous issue could be avoided. And I also note the difference between click 'cancel' and click 'x' in this way, By clicking 'x', the form will forced to close and this cannot be stopped. By clicking 'cancel' button, i can decide if i really want to close form.

Forum Post: Error During Using calcVal for Calibration and Performing Temperature Sweep
Hello, I am using Virtuoso version IC6.1.7. I would like to perform a very simple calibration (transient) simulation in ADE Assembler, where I run two simulations. Let's call them calibration and main_test. I have two variables. They are called myVar and temperature (is the temperature basically). In calibration, I measure one voltage output (scalar, let's call v1) at nominal conditions (process, temperature and voltage). In main_test, i provide v1 as a the value of myVar by using calcVal function as: calcVal("v1" "calibration"). Additionally, I would like to perform main_test for two temperature values that are 25 and 30. For that, I check the box next to temperature under the design variables section of the main_test simulation and enter 25 30. The simulations works well for calibration. However, I get the following error in main_test: ERROR (SFE-1996): "input.scs" 13: Parameter 'myVar': Cannot run the simulation becaise an unknown parameter 'nil' has been specified in expression 'nil'. Correct expression and rerun the simulation. As an extra information, if I enter a single value for temperature, main_test runs without any problem. Only multiple entries result in failure. Many thanks in advance for your support. Best regards, Can

Hi Marben, Just an observation here. Since a terminal can have more than one pin and so figure, would it be correct to wrap with one more foreach rather than "car(insterm~>term~>pins)? -Ramakrishnan

Forum Post: Frustration in getting bugs fixed
I tried to work with EMA-EDA tech support but they only respond to simple problems that they can easily provide a solution. Anything that is a bug that requires more work to respond they basically never respond. I have also tried with Cadence and CCR's but spend lots of time trying to get them to see the problem and then it goes to R&D and never get any responses. I ask and ask when it might be implemented and never get any answers. Is there anyone else I can contact to get bugs fixed quicker. Thanks

Forum Post: How to update the netlist (input.scs) from extracted view after QRC extraction
Hi, I am going to change the layout, then do PVS LVS and later PVS QRC to get the extracted view of the layout. In the next step I plan to do simulation in command line. If " input.scs " is ready by using spectre command it is easy to do the simulation. However, after the layout extraction I do not know how to generate the new netlist from command line. Would you please help me to figure out this problem? Thanks for your help Mohammad

There is this trace that can't be moved or deleted. Every time I try to edit it, "No such child. Contact Cadence customer support" message appears in the command line. After running database check, dbdoctor reports "POINTER TO CONNECT LINE INVALID" Error cannot be fixed. Anyone has this problem before and know how to fix it. Please advise. Thanks

Forum Post: RE: Error During Using calcVal for Calibration and Performing Temperature Sweep
Hi Can, In your case you are using calcVal and also having a local sweep. You are trying to pass a value from (single point) calibration test to (multiple points) main_test and the propagation (1 to multiple) cannot be done without clarifying what exactly you want to do. Thus it does not pass the value at all in the end and nil is printed in the netlist for myVar. So for your case, you need to add arg ?getFirstSweepPoint to specify that you want the first v1 value of calibration test (even though there are not more v1 values in your case!). So the calcVal expression should be like below: myVar calcVal(“v1” “calibration” ?getFirstSweepPoint t ) After adding the above it should be ok. Regards, Dimitra

Forum Post: Rotating not 90 degrees
Greetings community! I am an engineering student and just began to use OrCAD Capture CIS Lite for extremely basic resistor circuits. I am usually only using the program to draw the circuit and use other programs for analysis. My question (and I have searched everywhere) is how to rotate a component at something other than 90 degrees? I have read a few threads on this but the information is really old and it appears the method for doing this has changed. Is there anyone that can help me out? I am simply trying to rotate a resistor to 45 degrees rather than being vertical/horizontal. I am using version 17.2. Thanks in advance!

Forum Post: RE: How to find the coordinates of an instance's PIN?
Thanks, Marben, That was actually the output I was expecting. However, I seem to get nil as the output. The instance is a pcell. Maybe the pin was created incorrectly in the pcell.

Forum Post: Query regarding the ncelab: *F,CUHUNL fatal
Hi Team, I set up a very basic mixed signal simulation environment with two inverters (one in sch and the other in verilog). I set up the HED with functional view for the verilog inverter and its working fine. But when I bind the verilog inverter with a verilog file (using "Specify Reference Verilog") from my local which has a UDP instantiated with in it my simulation failed with the fatal ncelab: *F,CUHUNL. I understood that since the module view was selected when I referenced my local verilog file, the same has been added to the stop view and that is where it was failing. Is there any solution to it as I have lots of UDPs and it will be time consuming to write modules for them? I beg your pardon if I have posted my query in a wrong place. Thanks and Regards Susanta

I have never experienced a single bug fix from a report since 1994 until I worked for HP for a short while. There we had basically overnight service but since then it's one of the worst customer support experiences out there.

Forum Post: RE: Error During Using calcVal for Calibration and Performing Temperature Sweep
Hi Dimitra, Many thanks for your answer. Now the simulation works with no problem and I can perform a temperature sweep in main_test by having the first value of v1 obtained from calibration, used in all temperature points in main_test. My second step is to perform a Monte Carlo simulation including process variations and mismatch (i.e. performing the previous test for each Monte Carlo seed separately, by having the v1 value calculated in calibration for each Monte Carlo seed separately and assigned to myVar in each following main_test ). However, what happens is that the simulator assigns the v1 value obtained from calibtarion of the first Monte Carlo seed to myVar in main_test for all following Monte Carlo seeds. What should I do to have the different v1 values assigned to myVar for each separate Monte Carlo seeds? Many thanks in advance. Best regards, Can p.s. The temperature sweep in main_test should still be applied.

Forum Post: how to automatically add vdd vss sub to the standard cell symbols
Hi All, I have a 5V standard cell lib for digital usage. I would like reuse the lib and make another one for analog usage. We prefer to have the power (VDD), ground (VSS) and Substrate (SUB) showing up in the symbols for convenience. Does anyone have a good way to add VDD (B) VSS (B) and SUB (B) to the currents symbols? It would be better to put VDD on top, VSS and SUB at the bottom of each symbol. Thank you very much for sharing. Andrew
