Source Synchronous Interface Output Constraint
Hi, I am trying to write timing constraints for FPGA - SDRAM communications. I know as per Intel documentation, the formulas are: output maximum delay = maximum trace delay for data + tSU of external register - minimum trace delay for clock output minimum delay = minimum trace delay for data – tH of external register - maximum trace delay for clock Now, For my design I have the maximum & minimum trace delays from PCB design of the board (considering 16 data lines between FPGA & SDRAM. I also have the tSU from SDRAM data sheet. My questions are: 1) To calculate the board delay, I looked at the data (D0-D15) trace length between FPGA & SDRAM, using the PCB designer tool. Using the trace length and other parameters, I calculated the min & max board delay between FPGA and SDRAM. Is that the right way of doing it? 2) How can I calculate the minimum & maximum trace delay for the clock? There is only (clock) line going from FPGA to SDRAM, so it will have only 1 delay value. How do I calculate min and max for the clock trace? Please advise Thanks Sahil897Views0likes3CommentsQuesta lpm CycloneV library not found
Hi, I have been using Quartus Prime Standard & Altera-Modelsim software for my design on cycloneV FPGA device for couple of years now. Last week I installed Questa Intel software to replace the Modelsim software. All the rtl files compile fine, except one lpm IP module. When I try to compile that lpm IP module, it generates an error: "(vcom-1598) Library "cyclonev" not found". (screenshot below) I am not sure why that error is getting generated. Do I need to install any additional cycloneV device packages for the Questa software? Or are there any packages that I need to move from Modelsim to Questa? Kindly help! Thanks1.4KViews0likes4CommentsQuartus Prime Floating License with Standalone Modelsim License
I am using Quartus Prime Std floating license and Intel- Modelsim floating license. My question is Can I use Quartus Prime Std floating license with Intel_Modelsim Standalone license? Will be there be any issues with this configuration? Please advise! Thanks911Views0likes2CommentsRe: Quartus Prime Floating License Renewal Invalid LAC
That is right. itorderfulfillment@honeywell.com is the Honeywell IT team who procured the license renewal on my request. But Still I am the user. Kindly advise what the next steps should be. I really need the license to renewed as soon as possible. Thanks2KViews0likes0Comments
