Hi Friends,
What is your next generation VLSI project?
Do you mean next generation process or next generations algorithm?
There are many place and routing tools?
But it depends on your projects type.
If your design is full digital or mixed type, you can use Apolo tools from Cadense.
But your design is analog, you have to use manual type layout tools like Opus from Cadense.
Cadense tool is more popular between place and routing engineer.
Drawing is not so much important.
The most important thing is verifying your layout design.
Are you consider about it?
We call DRC and LVS.
If you use back-end design house, you need not consider about them.
But if you have to layout by your self, you should handle DRC and LVS rules.
It is not easy to stater.
Be careful about verifying.
I hope you project is going well.
Thank you.
