Can anyone explain the step by step procedure in creating module for design reuse.
I have four same power supply in my board
So draw schematic of power supply and linked it to heirarchial block .
Then i created the netlist and opened it in allegro and routed pcb.
How can i create...
I am working with a pcb with 4 SDRAM chips (TSSOP package) .Data, address ,control and and clock are connected to all the 4 SDRAM chips. What is the routing strategy that i should follow.What should be the length of the signals.
Thanks in advance
I have been drawing schematics in Capture CIS for past few years.
Now we have switched to Design entry HDL,
Is there any tutorial for studying this.am new to this tool
Can anyone help me
Thanx in advance
I have been using allegro 16.0 still havent tried auto routing in any pcb's
Can anyone guide me in auto routing
Would like to know about spectra too
What is the difference between spectra and allegro pcb editor
Can anyone tell me about auto routing features in allegro 16.0

I have drawn a schematic in capture CIS
While importing it to allegro rats net for the net gnd is not showing.
what may be the reason for this?

I have a doubt regrading the schematic library.
I created some schematic symbols for IC
but they are to be created as a single part.
So to combine them to a single part,
I created a new part (heterogeneous) in the library and saved it.
Then opened those single parts and copied them to...
manual vs autorouting
hii all experts,
I havnt done autorouting....
but i think manual routing is much better,
what do u people think.
i am now working on a PC motherboard.
what should i do .
auto routing ya manual routing..
which one u prefer.....
Can anyone help me in autoruoting in allegro16.0
I have routed PCB's manually only.
So i am not familiar with the constraint settings which are to be given while auto routing the board.presently i'm working on motherboard.
it needs to meet with several constraints like etch...
I want to know how the pins of a component are swapping.
It is a BGA component so made as heterogeneous part in the schematic.
Pins which are to be swapped are put in the same pin group,but while trying to swap the pins..
Its showing a message --> " Pins must be on the same...
Can anyone provide me instrctions for creating a device file.I want to swap the pins of BGA which i am using now. It has 688 pins.I am using Allegro 14.2, While trying to swap the pins its showing 'swap code is zero'.
Its very urgent.
Thanks in advance.
I have a doubt regarding allegro 16.0.How can i add a new via in this version?
I have made a via named via_56_28,I want to use this via in my board instead of the default via.How can I import this to the board file.
I also want to know how the spacing constraints are given?
ie line to...
