I'm upgrading a design, and I'm in the early phases of choosing a vendor. I'm trying to compare parts based on experience I've had in the past, so I'm focusing on block RAM clock to out delay as a critical performance number: Altera M4K vs. Xilinx Block RAM clock to out delay, non-registered outputs: Stratix-II -3 2.46 ns Stratix-II -4 2.828 ns Stratix-II -5 3.393 ns Xilinx-V4 -11 1....

Hello everyone, I have a rather high performance design that acts as a high through-put data path with some DSP manipulation on the way through. I had been rather certain that I was going to move through to production using Stratix/Stratix II parts. However, the other day I sat down with a distributor who was able to point out some very interesting items for comparisons with the V4 chip...

I'm trying to increase the speed of my Stratix design and would like to change which FFs are turned on within a DSP block. The Stratix handbook shows the DSP path something like this: [ FF ] [ X ] [ FF ] [ + ] [ FF ] where [X] is the multiplier block, [+] is an accumulate block and all registers are optional. I don't use any of the accumulators, and I use pipeline_delay=2 going throu...

I am having problem with my NIOS Stratix Board. I am not able to download just my own, simple, compiled VHDL code onto the Stratix FPGA. The device is EP1S10F780C6ES.

I tried loading ...

Hi, all. This is Tomoya greeting from Japan. I would like to hear about Altera Stratix-II ES(engineering sample)/MP(mass production) differences. Here is background of our isse (we're facing); We'd made three DDR evaluation boards using Altera Stratix-II EP2S180/130. It has DDR interface, DDR memories, and many IOs (GPIO: General purpose IO). At first, we used EP2S180/130ES (engineer...

Hi, Has anyone got NIOS software to boot from Flash? I'm working on a Stratix II-based design with onboard NIOS and peripherals (16MB flash, Ethernet, SDRAM etc). The Flash, Ethernet, and SDRAM components are wired to the Stratix-II via an Avalon tri-state bus, similar to the design on the Stratix Edition Nios development kit. A single Nios CPU core is running at 50MHz.on the Stratix II....

Hi, Who could enlighten me with the followings: I need to interface a SERDES transciever from a VIRTEX5 FPGA with a STRATIX II IO. Things would be easiest if I'll have a Stratix II GX instead of Stratix II, but the GX FPGA has no HARDCOPY II structured Altera ASIC corespondent, so I can't use a GX because of finacial reasons (and huge ball numbers, improper for this design). How could I...

Hello All, I am trying to interface the on-board SRAM (IDT71V416 256Kx16) to the FPGA on the Stratix. It is not installed among the library components in the SOPC builder so I cannot instantiate it automatically.
