[PCB_FORUM] Re: Relative prop delay

 

Hey Julian,

 

Thanks for the reply.

 

It looks like there are several ways to put in a pin delay.

I think I'll try the schematic package driven one first.

 

Regards,

Gary

File - Import - Pin Delay

 

The text file should look like this:

 

PIN DELAY 

REFDES U56,U57

DEVICE FBGA-1156

UNITS PS

N30 82.27

N31 93.84

M33 102.15

N33 103

N32 93.47

......

 

 

Thanks,

Julian

Hi Gary,

 

In order to include the package lengths in a component you need to add
them to the packages section of the schematic symbol. These values will
then appear in the Pin Delay columns.

Hey guys,

 

It has reached the point where I have to consider the package length
when matching some nets.

I am using Relative Propagation Delay in CM, and was wondering if anyone
knows how to include the package lengths?

I thought maybe the Pin Delay columns, but they are grayed out.

 

Any ideas?

 

Regards,

Gary
