Creation of WorkView symbols

(1 / 1)


John and I have just gone through our standard library and tagged the PINTYPE
attributes that need to be changed for the Logic Design Rule Checker (LDRC) to
work. Once we have PCB make these changes it should be possible to get 
meaningfull DRC reports from WorkView.

In order for us not to have to repeat this exercise, I would ask that when you
define a new symbol you make sure that the PINTYPE attributes are set properly.
The choices are:
IN	input-only pin
OUT	always enabled output pin
OEM	open emitter/source output pin
OCL	open collector/drain output pin
BI	bi-directional I/O pin. This must be used for bidirectional data busses
	  if the LDRC is to work properly
TRI	tristate output pin. Use only for tristate outputs, not for I/O pins
ANALOG	any analog component pin or other pin you don't want to hear about
	  (like connectors)

If you don't specify the pin types, Leon will make a (usually incorrect)
guess as to what they are so please remember to specify.

Many thanks,
	Tim
