Hello All,

I am using ISE 12.1.

I downloaded the frequency counter reference design targeting Picoblaze and the Spartan 3E starter kit.

I can download the included bit file to my Spartan 3E board, and it runs successfully.

But, when I try to rebuild this design using ISE 12.1 and the included source files, it fails with error messages like:

XST failed:

Port <proc_reset> of instance <program rom> does not exist in definition <fc_ctrl>.

Please compare the definition of block <fc_ctrl> to its component declaration to detect the mismatch.

the reference design shows ISE 8.1 as the version being used.

I am using ISE version 12.1. Because of licensing going back to the older version is not possible.

Can someone suggest where to look for the problem or offer a solution?

Thanks,

Barry.

Barry, this is a duplicate of your other recent thread.  Posting duplicate threads in multiple forums is called 'cross-posting', and is considered a rude and confusing practice.

It would be good to stick with the one thread you've already started for this subject, and finish the discussion there (instead of here).

Sorry, I did not see they were related at the "Xilinx user community forums" level.

I thought they were totally separate.

Now that I know, I won't do it again.

Thanks,

Barry.

Good mornig ,

I am using ISE 12.1.

I downloaded the frequency counter reference design targeting Picoblaze and the Spartan 3E starter kit.

I can download the included files , then i tried to dowload bit file but I found this error :

ERROR:PhysDesignRules:955 - Invalid configuration (incorrect pin connections

   and/or modes) on block:<dcm_fixed_oscillator/fixed_osc_dcm>:<DCM_DCM>. 

Could you help me please ?

I just downloaded the ZIP file from the Spartan-3E Starter Kit reference design site to be sure that I was looking at the same original files as you. I connected a Spartan-3E Starter Kit and then used the ‘install_frequency_counter.bat’ to program the device with the ‘frequency_counter.bit’ file and it worked correctly. I happen to be using ISE v14.x but I have no reason to suspect a version between 8.x and 14.x failing.

I suggest you check your set up and describe in more detail exactly what you have done because the supplied BIT file is still working for me (after 6 years).

Thank you very much for your reply. it works correctly.

Now I trie to disply tow frequencies in  the same time , I changed the program in order to display tow frequency but i can't make the name of tow frequencies down.

I want to know how to change the display names of frequency.For exemple  Instead of putting in SMA imput put, it put  two names (for exemple SMA imput and DCM fixed oscillator).

Could you help me please?

Sounds like you are making progress. Sorry, but I do not fully understand what you are trying to do or why you are now having problems. May be it would help to look at another Spartan-3E Reference Design that covers the use of the LCD in more detail.

Initial Design for the Spartan-3E FPGA Starter Kit Board

This is the design shipped with the board. The embedded PicoBlaze™ processor controller scrolls messages on the character LCD screen. The rotary pushbutton switch controls whether the switches or the rotary button controls the LEDs.
