"printf" asking for input data

Hi, my cuestion is why when I ask the user to input data in the test bench with "printf" for my TOP.c not run?
NOTE: I am a new user HLS :)
Regards
 

welcome
Also besides Gabor's answer, please note that the testbench execution is wrapped into other scripts, so user input would not work because it's not interactive (if i remember correctly) so you can't do cin , gets , scanf etc
From the GUI, when performing csim there is the ability to enter input arguments to the executable - ie the ones passed to argv.
If you want to do user interactions, then you need to go to a command line and navigate to YOURPROJ/YUORSOLUTION/csim/build and run the executatble from there : it's call csim.exe.
As such I would recommend to avoid using user inputs in your testbenchs - but you can use loops or text files with 1000s of test values.
I hope this helps.

  • Query /report asking for input ? in Apex

    Hello all, my name is John and I am asking for help with the following,
    I am new to Oracle, Apex and SQL, PL/SQL (as you can tell from my query below.)
    I have the very basics of Apex (in that of making reports,forms etc).
    I created this query on a view in SQL Developer where it is asking for start and end dates to filter the report. , which is what I want it to do and returns the results I want.
    Now I would like to create a report in Apex where it asks for the between dates as it does in the posted query, When that is done I want to pass it to the bipublisher report for pdf printing.
    I am running this query as a totals report already (without the line with WHERE clause query asking of course.) in an apex application, crude as it may be.
    I have it running as a Interactive reports and can filter the dates that way of couse but I want to learn to create the user input type query/report in Apex.
    I have been reading that I would need to use a "pl/sql anonymous block with a "declare' and a page process?. (gettting confused in the "declare" variables and the execute sections)
    I have looked at numerous samples and still do not quite getting the blocks down.
    If you could point me in the right direction of where to go or better yet if someome could show me coding on how to get this to work in apex report/query (s)?
    Slow learn I guess
    I am using APEX 3.1.2 on 11g database.
    Thanks in advance for help on this.

    Hi Martin,
    Thank you for the information, it is a real help to me and gives me more insight toward my learning .
    It took me little while , the condition had to be modified a little bit
    (had to put parentheses around the :PXXX_START_DATE .... END_DATE, and remove the period to get it to work).
    where (:PXXX_START_DATE) is not null and (:PXXX_END_DATE) is not null
    It does work to the sense it shows the start and end date fields and the button and the report results below that, and you can enter the dates and the results change.
    Looking at my question, I should have been a little more clear in the fact I want query to ask for the dates first in a pop up type window, when you press the "Show Report" button,
    and then branches off to show the report. That is the reason I think, I referred to a block or procedure to acomplish this?
    Thanks and still learning
    John

  • Special GL  asking for Due Date

    Hi SAP Gurus,
                When I am trying to post the customer invoice with t.code F-22 and put the Special Ledger indicator it is asking for Due Date as a mandatory field but it should not be because of the payment terms.
    Is there any configuration I can use payment terms with special GL indicators for customer and vendor documents.
    Is there an option to get the payment terms from the company view when we are creating invoices in special GL indicators. Because the due date that appears, instead of baseline date, payment terms and days as in a common invoice.
    Regards,
    Sim

    Go to T.Code - OB41 (Field Status for Posting Keys)
    Selct Posting Key - 01 & Go inside
    Go Inside to Group - Payment Transactions
    & Check Out whether Due Date Field is with Required Entry or not. If it is so then make it Optional.
    Similarly, Check out Special GL Reconciliation A/C . Through FS00,Check out the Field Status Group of the same (Mostly, it will be G067- Recon.A/Cs) & make the Due Sate Field Optional there as well in Payment Transactions.
    Regards..

  • I am unable to sign into icloud.  When asked for my date of birth I receive a message that my dob does match Apple's records.  I don't remember setting a different password for icloud.

    Since I replaced my iPhone 4 with the 5s I have been unable to access icloud.  When asked for my password I receive the message that it is not valid.  wehn using the security questions the system does recognize my date of birth. 

    You can have the password reset sent to the email address associated with your ID, as explained in the second option here: http://support.apple.com/kb/HT5787.  If you don't have access to the email address, you'll have to contact Apple for assistance by going to https://expresslane.apple.com, then click More Products and Services>Apple ID>Other Apple ID Topics>Lost or forgotten Apple ID password, or by contacting the Apple account security team: http://support.apple.com/kb/HT5699.

  • ECATT - How use external file/new variant for input data

    Good day,
    I want to use an eCATT created by someone else for another request. I want to be able to specify my new input data based on the new request WITHOUT generating a new Transport. Same thing as I'm doing for the CATT ... the CATT is transported but only the input data change depending on the request without generating any transport.
    How I build my new input file and how to use it? I tried to download my variant but the only possible format is XML and it's very hard to build a new file based on my request.
    Thanks for your help.
    Simon

    Hi,
    Can you tell me how you are generating the xml file. My guess is you are downloading the Test Script/ Test Configuration. In that case it creates an xml file.
    As mentioned by Ajay, In Test Configurator / Test Data -  you can create the internal variant first, i.e assuming you have already created parameters.. On the top, you have a download button "Download Variant". This creates a .txt file. You can open the file in excell and edit it.
    For the next test, you can select external variant and give the modified file path name.
    Let me know if this helps.

  • Asked for graduation date when ordering CC for students; does that mean it will be cancelled then?

    Adobe asks for your graduation date when ordering Creative Cloud for students; does that mean it could be cancelled by Adobe after that date? It states:
    "This price is valid for a full 12 months. After that, we'll renew your contract automatically unless you cancel. We may verify your academic status at any time and if we find that you don't qualify, we may suspend your account. The price is subject to change. If we ever need to make changes like this, we will always notify you beforehand."

    Pseudonamed, It will not be canceled it will Auto-Renewed, However if your verification with the educational institution fails, then your subscription can be suspended.

  • Why pop up is shown to ask for inputing sales order when using COR1

    I want to create a process order with order type PI01, but pop up window is shown to ask for sales order when using COR1.   I suppose there is something wrong with material master setting, but I've never set classification to this material.
    Please help.

    Hi Nichole
    Is the material assigned to any MRP group , if yes then check the  config settings on t-code OPPR, if stg group is assigned. also check the matrial type to default MRP group assignment settings in SPRO>production>mrp>MRPgroup> Define MRP Group for Each Material Type.
