DxDesigner to Allegro flow - netilsting configuration

Greg,

I would go ahead and change the character limits in the CFG file to match what Allegro maximum characters limits. I have found that the CFG File provided in DxDesigner (Viewdraw) is very dated and I have a running list of changes to CFG file on every new release of DxDesigner.(We have a local CFG file that we freshen when rolling out a new DxDesigner release) Here is the max characters limits from the Allegro documentation

Field Maximum Number of Characters
package name 30
device type 30
function designator 30
reference designator 30
function type 30
pin number 30
slot name 30
swap type 30
pin name 30
net name 30 --> We use 27
property value 79
tolerance 79
user part number 79
value 79

We reduced the net name maximum number of characters to 27 to prevent issues when placing modules in the design because Allegro adds an underscore and the module name to the end of the net and package names which will cause an error if you exceed the character limits.

One final thing to note. I believe in Allegro 16.0 the max limit is 255 characters via an environmental variable "allegro_long_name_size" for new designs so you will be updating the CFG file once again to bump the limits.

Hope this helps,

Thank you very much Mike,

However, the main attribute that the engineer doesn't want to change is the PART_NUMBER attribute - and he refuses to change it from the default 11!!!

I set it at 25 and 30 with no issues.

Now I have to figure out how to get rid of his 'errors' so that he stops complaining.

Thanks again,

Greg
