PDN Tool Custom Lmnt Issue - PDN Tool Custom Lmnt Issue Hello FPGA Forum, having an issue with the fpga pdn tool (device agnostic from website): The value of “Custom-Lmnt” in the Decap Selection Tab is not being set to the capacitors “Custom-Lmnt” from the Library Tab, instead it’s being set to the “Custom-Lmnt” of the capacitor value that’s in the same relative position in the Library Tab. For Example see the attached screen shots below of the Library & Decap Selection tabs from a design I’m doing: In the library Tab the 4.7uF capacitor on the bottom row has it’s “Custom-Lmnt” set to 0, and the 0.001uF capacitor on the top row has it’s Custom-Lmnt set to 1.19nH. So in the Decap selection tab was expecting the Lmnt of 4.7uf to be 0, but instead it’s 1.19nH. Note that the ESR & ESL in the Decap Selection are being picked up as expected, i.e. in this case they’re 0 in both the Library & Decap selection Tabs. Can you please advise: Is this is a bug or if not how I'm mistaken? If a bug: When can we expect a fix ? Is there a way to work around the spread-sheet password protection so we can implement a fix while the spread-sheet update is pending?

Thank you. regards, Farabi Replies: Re: PDN Tool Custom Lmnt Issue Hi Farabi, Unfortunately, the best I can do at this time is to let you know I've downloaded the 28nm_pdn_hid_04_27 PDN tool and that's working. -John Replies: Re: PDN Tool Custom Lmnt Issue Hi John, I am afraid this is bug in PDN calculation. I need more information on the device in order for me to file a bug report, you dont have to give the exact part number, but device family information would do. regards, Farabi Replies: Re: PDN Tool Custom Lmnt Issue Hi Farabi, The PDN Rev is 1.1, see screen shot below. Program is classified, can't share device. -John Replies: Re: PDN Tool Custom Lmnt Issue Hello John, May I know what version of PDN and for what device are you using? regards, Farabi
