Hi, may I know why sig3 donnot need ISO cell? Because pd_gated_aon domain also may turn-off power

Hi， I load the UPF script with Design Compiler, and find a ERROR message "Error: The supply net VCCH specified for the isolation strategy isol_sig_from_aon_pgd does not exist in the power domain pd_aon in which the isolation cells will be inserted. (UPF-103)", I think this is because the location of "isol_sig_from_aon_pgd" is parent, and this isolation will be inserted to pd_aon domain, but in which this is no VCCH supply net, so it causes a error.

Is this ever needed for FPGAs?

Thanks for creating this helpful video! When we do power analysis using let's say PrimePower and load this UPF, can we tell PrimePower to calculate power for a particular power state?

Hi Amit, I am glad you liked it. Unfortunately I have not worked on power analysis therefore I will not be able to comment.

Hi, May I know why is PGD_ON pst state is required? In starting there is a req as"Logic inside aon_pgd_wrapper can be power gated but won’t be power gated when pgd_wrapper is powered ON."

@vlsitutorials3484 3 жыл бұрын

Hi Samhitha, thank you for pointing it out. PGD_ON pst state is not required as it contradicts the assumption (I might have included it to consider all the 4 possible states of VDDH_gated and VDDL_gated as if it is a truth table). I will pin your comment so that everyone will know. Also, I have not included GND in the power state (an user named __RMK__ pointed it out in the comments)

Nice explanation..Keep it up.. You have posted one video. Request you to please do post more videos. There are lot of folks needing guidance in VLSI....Thanks for the effort...

@vlsitutorials3484 3 жыл бұрын

Thank you, I am glad you find it useful. Making videos, especially putting together slides for presentation takes a lot of effort; due to work and personal commitments, I am not able to make more videos. However you can visit my blog vlsitutorials.com to check out other topics.

Impressive. Please make a video for the CDC also.

@vlsitutorials3484 3 жыл бұрын

Hi Robin, I am glad you find it useful. I don’t want to make a video about CDC as there are plenty of good videos about it on youtube, please refer those. :) However I may be uploading a video about Scan and ATPG concepts in near future.

@robinjohn7816 3 жыл бұрын

@@vlsitutorials3484 Thanks. That(scan/ATPG ) will be great. Basically I didn't find any good videos which explain cdc constraints like how you explained STA constraints in your blog. I found it's very clearly explained in your blog.

Thank you for your insights! I have just started learning about UPF, may I know why GND was not included in create_pst command along with VCCH, VCCL, VCCH_gated and VCCL_gated?

@vlsitutorials3484 3 жыл бұрын

Apologies for the late reply. Thanks for pointing it out (I might have ignored it because it is ground). But we need to specify the value GND can take on before using it in create_pst, like this - add_port_state GND -state {gnd 0.0}

Really good explanation . Actually, I am trying to learn the UPF basics. Is there any web link, that I can find the example RTL, UPF for the same .

@vlsitutorials3484 4 жыл бұрын

Karan Praba I am glad you find it helpful. I am not sure if any site has this information. May be I will try to write a RTL corresponding to this UPF and update in my blog. But if you want to learn about upf command syntax and other information, you can check here - vlsitutorials.com/upf-command-syntax-low-power-vlsi/ vlsitutorials.com/power/
