There really is no direct memory interface. The best you can do is look for tools that can use the ".raw" files which capture the data from a simulation.I am simulating Recurrent Neural Network(RNN) with Ltsipce simulator. There, I need to store intermediate output and use it later.
Can you please suggest me how can I use memory in Ltspice ? Or any link that will help me?
Thank you so much. Can yo suggest any of these tool?There really is no direct memory interface. The best you can do is look for tools that can use the ".raw" files which capture the data from a simulation.
A behavioural voltage source using the delay or round function perhaps?Can you please suggest me how can I use memory in Ltspice
Backpropagation through time training algorithm is simulating to train rnn.hi santial.
I wonder if some method of LTSpice .wav I/O file manipulation could be used.?
Do you have a simple example of a RNN simulation problem.?

How long should the memory retain data?
I have not had any use for such tools, but I have seen them discussed on the LTspice users group at groupd.ioThank you so much. Can yo suggest any of these tool?
Thank you so much . But I need to use the channel outputs after some delay (for example after 100 milliseconds) . in the same ckt again. Please suggest how can I put delay. thank you.hi santial.

your idea is working. Can you please suggest, how we can perform time operation on signal in ltspice? for example signal scaling, signal shifting and signal reversal.hi santal,
Since I thought that the 'wav' approach could be a possible solution, I see that others have already posted idea's on the same method. Ref the posted link.
The simple tests I have just run, show that sampling rates of 100K are no problem, also multiple parameters can be 'saved and recalled'.
Note the interesting use of the Spread Sheet data in that link.
I am not upto speed on RNN, so rather than attempt to learn the full subject, which I have no projects in mind for which I could use RNN, just post a simple example of what you want to achieve.
I can then try some idea's

I mean latter one. I also want to perform signal scaling in time i mean stretching of signal. Can any function (.func ) be, that perform it? or .ascDo you mean reverse signal polarity, or reverse signal in time? If the former, then use an op-amp. If the latter, it can be done with a wav file in Audacity.
