Manual routing or auto-routing in PADS logic

[=lei=]

Hi all,

Introduction:
I am a beginner for using PADS logic , Layout & Router. I have to submit my project(SDIO card) by this week. Appreciate if anyone can give any ideas or solutions for my doubts. Thank you in advance.

Situation:
I am using Router for auto routing. As i my design involve in ENE(CB714) IC and there are many nets are unroute within this IC. After auto route , there are only 70% completed. The rest of 50 nets i have to route manually.

As a beginner, I only can complete about another 20 nets. the rest still remain unroute.

What i Try:
My design is 4 layers. I had tried VIA insertion. trace mil is 8.
I tried to replace the components .

Re: ROUTING problem

Don't Auto route.Manually route all the nets and fix, remaining nets do autoroute.

Re: ROUTING problem

Hi,


As a beginner its not at all good practise to go for autorouting, you should enjoy routing manually,now.

First try to route all critical (important signal) signals manually,then you can auto route rest of the signals,By doing this, you can check the feasibility of the routing and moreover you can squeeze the trace,subsequently it will be easier for autorouting.

Remember to always to route critical signals first manually,try this ,you might see the difference in routing.

ROUTING problem

manuall routing is better than autorouting when ur dealing with high speed signals.
