## Model Summary

The VeriGen model is 2B parameter model is a fine-tuned version of [CodeGen-multi-2B](https://github.com/salesforce/codegen), trained on [Verilog Dataset](https://huggingface.co/datasets/shailja/Verilog_GitHub), with a context length of 2048.

## Use

### Intended use

The model was trained on Verilog from GitHub and textbooks. As such it is _not_ an instruction model and commands like "Write a module that implements a 2-to-1 Mux." do not work well. However, by additing a partial line of module header like "module mux" in addition with the text in the prompt turns it into a capable Verilog teaching assistant.

### Generation
```python
# pip install -q transformers
import torch
from transformers import AutoTokenizer, AutoModelForCausalLM
# Prompt
prompt = "//module half adder "
device='cuda'
# Load model and tokenizer
model_name = "shailja/CodeGen_2B_Verilog"
tokenizer = AutoTokenizer.from_pretrained("shailja/fine-tuned-codegen-2B-Verilog")
model = AutoModelForCausalLM.from_pretrained("shailja/fine-tuned-codegen-2B-Verilog").to(device)

# Sample
input_ids = tokenizer(prompt, return_tensors="pt").input_ids.to(device)
sample = model.generate(input_ids, max_length=128, temperature=0.5, top_p=0.9)

print(tokenizer.decode(sample[0], truncate_before_pattern=[r"endmodule"]) + "endmodule")
```


### Attribution & Other Requirements

The pretraining dataset of the model was not filtered for permissive licenses only. Nevertheless, the model can generate source code verbatim from the dataset. The code's license might require attribution and/or other specific requirements that must be respected. 

# Limitations

The model has been trained on Verilog source code from open sources. The predominant natural language in source code is English, although other languages are also present. As such the model is capable of generating Verilog snippets provided some context but the generated code is not guaranteed to work as intended. It can be inefficient, contain bugs or exploits. See [the paper](https://drive.google.com/file/d/1cN-b9GnWtHzQRoE7M7gAEyivY0kl4BYs/view) for an in-depth discussion of the model limitations.
