FPGA's with on-chip PROM?
Hi all, I am working on a new design and have chosen the Spartan 6 family FPGA for it. I was looking to see if there is a an on-chip PROM on any of the Spartan 6 FPGAs. I could not find about it in the datasheet. But if there is something that I am missing or if there is any other series of FPGAs with on-chip PR... 19 Mar 2010 18:58

Any advice on which is the best book on CMOS digital circuit design?
Hi, I want to buy books on CMOS digital circuit designs. Any advice on which is the best book on CMOS digital circuit design? I know the best textbook on software programming is a book written by MIT 4 professors "The Introduction to Algorithms". Knuth's "The Art of Computer Programming" 1-3 volumes are good,... 31 Mar 2010 19:55

Nested interrupts in Nios system and hung system
Hi, The setup is the following : - a stratix II GX hosts a Nios IIe - one timer running continuously at a period of 1s, priority level 6, the handler for this interrupt has some functions calls to usleep and performs polling, this handler is made interruptible via the use of the alt_irq_interruptible and alt_ir... 17 Mar 2010 12:27

VHDL-2008 'protect
Hi All I'm looking into the IP encryption that VHDL-2008 now offer's to use on our code. I've got the latest Ashenden book which has a small chapter on it, but was after other reference material and even working examples. My main query centers around how do you encrypt the code. Are there 3rd party tools... 15 Mar 2010 19:27

Awkward Arithmetic
I am converting an integer equation to use numeric_std data types and it looks rather awkward. Here is the equation... PhaseStep <= (IntgrPhase + (PROPGAIN * DataCount) + FreqStep) mod MODULUS; The names in caps are integer constants, PhaseStep and FreqStep are unsigned while IntgrPhase and DataCount are sign... 22 Mar 2010 14:12

Memory Blocks in Arria II GX Devices - mixed port read during write
Hi, We have generated altera ram ip (RAM: 2-port) from Memory Compiler in MegaWizard Manager. We are operating in mode Mixed-Port Read-During- Write as mentioned in aiigx_51003.pdf (pg no:3-18, fig no:3-20). When we simulate this ram in modelsim the behavior of ram in this mode is not matching with section 3-20. o... 15 Mar 2010 07:51
