Re: Probing phase
Steve Kale
¿ªÔÆÌåÓýOk I see that in the log. ?But I don¡¯t get prompted with any error for which I must ¡°press ok to continue¡¡± which would lead me to look at the log in the first place.Fine¡ so (1) there¡¯s an error in the?2SC6144SG sub circuit from On Semi which raises log errors with respect to that sub circuit if all the Qd44vh10 pass transistors are replaced with?2SC6144SG. ?(2) If they are not, then LTspice tells me there¡¯s a missing Qd44vh10 model definition when indeed there isn¡¯t. ?(3) If all pass transistors are Qd44vh10 and the Spice directive in relation to the 2SC6144SG sub circuit is not ¡®commented out' in the schematic then LTspice tells me the model statement for Qd44vh10 is missing when it is not. (4) If all pass transistors are Qd44vh10 and the?2SC6144SG subcircuit statement is commented out of operation then all works just fine.? For (1) the problem is in the log but with no ¡®flag' that the log should be checked. ?With (2) and (3) LTspice points me to a problem that doesn¡¯t exist and not to where the problem does exist.? It took a lot of backtracking to identify that commenting out the?2SC6144SG sub circuit statement solved the problem. Of course then an examination of the material that needed to be commented out was readily done. It might well have been more obscure to identify had the?2SC6144SG sub circuit been one of many included via .inc statements. Better that LTspice actually alerts the user to the problem at hand rather than to an area which is just fine.? Let¡¯s perhaps end this sidebar regarding the?2SC6144SG sub circuit here. The issue is now fixed / no longer needed. I still have outstanding questions with respect to probing phase for which I would be very grateful of assistance.? Thanks in advance Steve EDIT: ?just saw John¡¯s post. ?The Qd44vh10 model is fine with respect to the device name / model name. ?The problem is with the 2SC816144SG sub circuit statement (with the .endl error noted by Philippe) and that LTspice points to an error with a missing Qd44vh10 model definition rather than an error with the 2SC816144SG sub circuit statement.?

Re: Probing phase
Hello
With all Qd44vh10 replaced If I replace .endL? by .ends I get no error or warning.

Re: Probing phase
John Woodgate
It looks very much as though your model isn't called *exactly* ' Qd44vh10'. There could be a leading or trailing space or another invisible character. Have you ever uploaded the model?

Re: No XP?

So why bother, unless you have no other choice? Many ADI parts have SPICE models.? SPICE models are SPICE models, and can be used in most any SPICE program, including LTspice, PSPICE, HSPICE, etc. ? ?"But similarly there does not seem to be older versions of LTspice than IV on LT's website?" Why would you want an older version?? I can't think of any reason. Sometimes, a company releases a program that is incompatible with older versions. ?(LTspiceIV -> LTspiceXVII is a minor example of that.? SwitcherCAD -> LTspiceIII -> LTspiceIV is not.) ?They keep the older versions because sometimes a customer needs the capability that only the older version has. As far as I know, there is nothing that an older version of LTspice can do, that LTspiceIV can't.? So there is no reason to use an older version. Andy |

Re: Probing phase
Steve Kale
¿ªÔÆÌåÓýHi PhilippeI don¡¯t want to labour the point as it is not directly concerned with my outstanding questions regarding phase. However, I do?not?get any errors if the?2SC6144SG?.subckt Spice directive is active (not commented) and all instances of Qd44vh10 are replaced with?2SC6144SG. ?I do not need to ¡°select OK to continue¡±. (This was what I had done when I tested the circuits with the higher fT transistor.) ?If there is any instance of Q44dvh10, then LTspice tells me I have a problem with the lack of a model statement for Q44dvh10 - even though I clearly have one. ?LTspice does not ever tell me there¡¯s a problem with the?2SC6144SG?.subckt Spice directive - not when I have an active instance of the device in the circuit nor when I do. That made finding the problem that much more challenging.? Regards Steve

Re: exporting large data file from LT spice
John Woodgate
¿ªÔÆÌåÓýEliminate the smaller set of steps and run sims with each step value successively, thus getting you smaller data sets that are more easily interpreted in Excel.

Re: Probing phase
Hello Steve
You wrote : A/ "assuming the pin order is indeed also a problem) " 'llI let others answer you about this point. B/" then, second, LTspice doesn¡¯t have a problem with the .subckt statement when it is invoked but does have a problem with it when it isn¡¯t " I suppose that by "invoked" you mean to say "used" : For me? as soon as there is a not commented command .subckt 2SC6144SG, the subcircuit is invoked even if there is no instance of this part. I don't agree with you : in both cases, as long as subckt 2SC6144SG is not commented, you have an error in subckt 2SC6144SG and LTspice don't want to run. If you choose the option "select OK to continue....." results are not what you are looking for. Morality : I avoid to paste subckt code inside a schematic. Regards PhB |
