Hi folks I would like to know the function of the chipscope ILA trigger and how to use it ?
RAM is used to store captured data. You define condition which will be used as a trigger for internal data capturing in real-time. After that you can download this data from FPGA through JTAG to analyse in PC. CPLD has no memory (just limited number of FFs), so there is no place to store captured data.
Now I want to see the internal signal in the fpga under test,so I use the chipscope but The chipscope does'nt work correctly,sometimes it can trigger however the match function I use.and the datas are always 0s,sometimes it can't trigger however the match function I use,and it displays waiting for trigger.I (...)
Hi everybody. I have some problems about chipscope 8.1i, please help me. I want to capture the address and data in a ram. And i expect the adress increase one by one,but the result is not as i expect,the capture address is disorder. I want to know why? and in the trigger setup there are WINDOW and N SAMPLES setting. i don't know much abot it
Hi I have a simple VHDL counter modul that I wanna debug with chipscope 7.1 on a Virtex II board: library IEEE; use IEEE.std_logic_1164.all; use IEEE.std_logic_unsigned.all; entity top is port ( clk : in std_logic := ?0?; cnt : out std_logic_vector(3 downto 0) ); end top; architecture behave of top is signal counter :
hi, In fact the chipscope only makes state analysis! When you are using the CLK signal for trigger/clock you can't see it! You must have an additional signal with higher frequency (for example x2 or more) and this signal is use for the chipscope trigger/clock, now u can see your CLK signal. For this you can (...)
Hi, I am using chipscope analyzer. after the trigger signal it shows the buffer has some data. but it is not full. Then I select Stop button. but It does not show buffered data. Is there anything I do not take into account?
HI friends I could get rid of the above problem by changing the clock not the trigger condition but It seems that i have to use the output of DCM(digital clock mananger) as clocking signal in chipscope . Please let me know whether i am going in a right way or not
Hello guys, I'M using chipscope pro 8.2 version. I have monitored the pin or buffer inside FPGA by assigning the ports and triggers and clks. Now when running "Analyse using chipscope", I can read the data from the desired registers as a time basis, that is I can only view a few set of samples (512 or 1024 upto 16384) which were selectable (...)
Hi, Just add reset signal, and give trigger on that, then press reset button, if in this case also same problem comes then your clock is not running. Make some counter which runs on clock (used by chipscopro) and assign 27th bit to led available on your board and varify. HTH, Shitansh Vaghela
You need not provide the pin number information while inserting the core. Insert the signals u need to tap, trigger, sampling clock, depth... compile the design again and then analyse thru chipscope analyser. Pls check the appropriate manual...
Hi, I have a problem with setting up the input data onto chipscope debugger. Say, I want to implement a simple 1 bit adder : entity CLA_1bit is Port ( A : in std_logic ; B : in std_logic ; C : in std_logic ; S : out std_logic ; P : out std_logic ; G : out std_logic) ; end CLA_1bit; architecture Behavioral of CLA_
Hi all I'm using MIG as DDR2 controller in virtex5. I created a cdc file for using chipscope. But while using the pins to trigger, only one bit of some registers appears in the list, but I need to trigger all (128 or 64) bits of the register. i don't know what the problem is.
1) What is the maximum speed at which we can watch Flip-flop value changing through chipscope ? I'd say it is directly proportional to your flipflop clock. If you use 300MHz clock, you can watch flipflop value changing at 300MHz rate. No doubt. But remember, that this is true only for synchronous designs.
Hi, Using trigger in chipscope, can I make multiple triggers, and every run, choosing just one of them to be the active trigger, while disabling the others? This way I don't need to compile all design when I want to change triggers. Can it be done? Thx.
Can we have two clocks for trigger signals to be monitored on chipscope? What is the way to monitor multirate data with chipscope? I have a design with an output signal with high decimation (>1000). I want to monitor both the high sample rate signal as well as the decimated signal. Is there any way out as we can add only 1 .cdc into a project.
try to use ddr2 sdram on virtex_5 lx110t board. I generate the example design by using mig. Then i simulate the design with modelsim and it works. Then i wanted to see the signals on chipscope but first of all i had clock problem of trigger, as you know if there is a clock problem with trigger so it means something is problem with clock pins (...)
What process? are you trying to halt the FPGA? you cannot do that unless you design it in such a way. I dont know why you dont want to use triggers. All chipscope is is a monitor - you need triggers to force a download from the continuous buffer on the FPGA to the PC.
Hi I'm trying to observe signals on waveform window in chipscope pro analyzer for viretex 7 FPGA on VC707 board. I get the message that "Waiting for Core to be armed, slow or stopped clock". FYI, I've hooked up the design clock port *clk_BUFGP onto board ocsillator 200mhz SYSCLK_P pin at FPGA pin E19 . I have set the trigger port as the Reset sig

Is there any way to trigger off of a 'event in vhdl that isn't the clock? Like a input from another module? jelydonut
I am trying to design a amp trigger at 6 meters. I intent is to create a trigger circuit via the coax at the load back to the amp. Maybe having a choke in series with a cap and resistor which is tied to ground, then using a switch short the choke to ground by passing the cap and resistor. Then on the output stage of the amp sense the change and fo

Hi , My board is connected to RS232 conector (COM port of PC). I would like to trigger two ckts through Hyper Terminal which are outside the board. How can i do it ? Can i use any other pins of RS232 other than Rx and Tx. This external ckt may be one CRO and one switch. Regards ~niks~
When I use chipscope 6.1i Analyzer to view the logic wave, I found that all of its port name are displayed as "DataPortxxx" or "TrigPort XXX" but not the PortName that displayed in CORE INSERTER when making connect? Is there any method to use/import the portname that displayed in CORE INSERTER? I think it's very stupid to rename it one by one ma
A A, Hi to all, These are some issues I noticed about xilinx ise6...I'd like to share with you, and benefit from your feedbacks I am working on Virtex-II FPGA...implementing mpeg2 decoding system on the V-II 4Milion...I use chipscope as a debugging tool to monitor internal signals and compare them with simulation... This is working fine
Here you can find more about oscilloscope triggering, including pictures for a better understanding.
keep away form external interrups at 89s52. I had the same unresolved problem and I had to find another way to trigger an interrupt. It would have been wonderful, the datasheet assures a clean interrupt, but it was't so. Maybe that generation of chips had some bugs.
Now i have to upgrade ONCE AGAIN to LATEST MATLAB, XILINX's ISE,SYSGEN,chipscope,EDK and others .The TERRIBLE THING is what about if i don't like ir or some of these things are INCOMPATIBLE . Every time i go through this is HARDSHIP. i can't keep the old versions .Some of these things ask you to remove previous installations .This is the case of M
Hope this helps... Ic is 4093 sch. trigger output is 585Hz with, R=10K, C=100nf configuration... Regards.
The modulation spectrum is done in Gated Mode. It will be measured only the bits that are in the middle of the burst (from 87 to 132). To do this test the Spectrum Analyzer shall be triggered. Check the spec ETSI 11.10 paragraph Not all the Spectrum Analyzers allow doing a Gated trigger test (you have to set up a window in the middle of t
Is there a way to calculate the histerisis value of a transistorized schmitt's trigger, given the value of the resistors and the Base-Emitter voltage drop ? Can anyone give me an example of it ? Thanks in advance....
I use "chipscope pro core generator" to generate the ICON , ILA and VIO cores.Now I have same questions. first ,if I must instantiate these cores manually in then HDL files? second , if so ,how can I connect the " control" signals of all these three cores. what are the "control" signals used for ? third , Now I connect the control signals
this is simply as follows.when the output (read voltage level at node "OUT")state is 1 and input is at,when output is logic one the source of tran M3 will be at when the input is increased to Vth1,tran M1 turns on,this will start bringing the potential of source of M3 towards when the input becomes Vth2+Vsource(M3),t
RB0 is a TTL input when used as a general purpose IO. Thus, the levels are 0.8V max for LO. 2.0V min for HI. When you configure it as an interrupt input, it becomes a Schmitt trigger input. That is, it has two definite thresholds at which the actual output switching occurs, with a fairly large hysteresis. A Schmitt trigger input buffer switches

hi all, I am using Phillips LPC760 emulator(5V power supply) for Schmitt based sine detection. There are two problems: 1) The Schmitt trigger output should follow the following rule as per the LPC760 datasheet: Vil(Negative going threshold) = -0.5V to 1.5V Vhl(Positive going threshold) = 3.5V to 5.5V. However the Schmitt output doesn't fo
in a book page 358 ,introduce design of the schmitt trigger, ?A general design rule for selecting the size of M2, that is β2,is to requre that β2≥5β1 and 5β3, since M2 is used as a swith,we requre that it be larger than M1 or M3.? I donn't understand this completely .Can anyone explain it better?
A while back, using some schematics and info I found on the net, I was able to make me a MIDI controlled switch. When it received a certain midi signal it activated a relay to close a connection on a 1/4" input, thus controlling a remote pedal for my guitar. Now, I have advance my setup a bit and am faced with a new challenge. I want to make a
Hello, everytime we talk about positive edge trigger and negative edge trigger flip flop. how do we design a postive edge trigger flip flop? how do we design it to trigger at the 5th positive edge trigger. what determines the umber of clocks it triggers at? hello, what i know (...)
anyone know what is function of CA3130 and 40106 schmitt trigger(NOT gate) in the circuit?? if CA3130 is comparatot, then how it compare the digital ouput from ADC with the reference voltage??? can state the condition??? thank you
I have a 6MHz noise sine wave signal from an oscillator which I would like to rectify. What would be a suitable schmitt trigger? Can they use analog input signals at this frequency? If so, can someone suggest a part number please. Thanks
In the following website you will find Schmitt triggers build around transistors, gates and opams .. Choose whichever you like or need .. Regards, IanP
schmitt trigger is for TTL signal: Vin > 2.0V => logic '1' Vin < 0.8V => logic '0' So, schmitt triger is not what you need. Look for something else like voltage comparators w/ hysteresis.
yes ! you can use chipscope For your design , but chipscope need block memory in xilinx FPGA for store data , you can set trigger in FPGA with chipscope try this link
Hi Jayant Thanks for your info. I went thruw that website. i could not understand wht does it mean by one needs to set trigger. how can i just monitor the internal buses while the fpga is interacting with software thru PCI. thanks in advance tama
