Conversion of a fully connected ANN to an SNN

I have an ANN trained on a certain dataset. The dataset is not available now.

Could you provide me with a code for conversion of a fully connected Neural Network to a fully connected SNN?

I am a beginner to Nengo and tried experimenting with example code but could not figure it out.

The NengoDL examples are a good place to start, specifically this one. The Loihi version of this example also goes into a bit more detail about firing rate regularization, and the CIFAR-10 example goes into even more detail, but builds the network purely in Nengo rather than converting it from Keras.

Could you please provide a sample code that converts to SNN from a fully connected ANN and not a CNN.
