Synthesis time Vivado 2020 with Kintex-7 and medium speed laptop

Jump to solution

Hi all! 

I am thinking of purchasing a genesys 2 Board from digilent which has a kintex-7 XC7K325T-2FFG900C on it. I have 3 FPGA boards (started with a small lattice board, then a medium altera board, then got a new laptop and a zynq board) and want to move up significantly from the Arty z-7 (which is still a great board) for some of my projects.

The problem is, Im wondering if some FPGAs are too much for some computers with not enough resources? specifically Im worried about synthesis and implementation time. 

If you put the same design on different sized chips, does the larger chip take longer to synthesize in vivado? Obviously larger designs take longer, but I dont want to buy the board if it is going to be to much for my computer. 

My current system is running vivado/vitis 2020.1 with dual core i5 and 8 gb DDR4 (laptop from 2017). Not the fastest laptop but it works really well even for the arty z-7010 board. I made a design last nigh which used half the BRAM on the chip and about 1/3 of the PL resources (took about 7 min to synth and implement which I dont consider slow at all).

would my system be okay with the kintex-7 part? Does anyone run this part with medium spec laptops? if it takes a long time its okay I can be patient, I just dont want it to time out or take a half hour to synthesize a few LUTs.

thanks,

-Dom

Never mind, after an answer on another forum, it sounds like it will be okay, sorry for the subjective question.
