2 port ROM not working on Quartus 18.1 Lite

AZeli · ‎03-22-2019

I'm trying to add a 2 port ROM and it doesn't work. All other mem devices work fine, but the 2 port ROM opens a qip file instead of the mega function wizard.

Hi Assaf,

"I'm trying to add a 2 port ROM and it doesn't work."

please provide bit more information like ,

where you are trying to add, which(FPGA) device you are using, any error, screenshot etc..

Thanks,

I tried generating the 2-port ROM IP using two Windows 10 based systems, and in one of them faced the same issue as you've mentioned. The Megawizard customization window does not open and a .QIP file is only generated. In the other system, the megawizard opens up and I was able to customize/configure the ROM instance and generate it successfully without any issue.

I think this has got to do with system-specific settings, have you updated the Java Run-time files to the latest? I believe the megawizard plugin uses JRE. I suggest you install the latest JRE runtimes, .NET Runtime packages from Microsoft and then try.

If all else fails, then uninstall and re-install the software .

Hi,

Thanks for the response. Here are the main details:

I am using Quartus Prime 18.1 Lite. My FPGA is a Cyclone 10 LP (10CL025YU256I7G).

When I try to create a single port ROM it opens the Mega core as usual. When I select the 2 port ROM it asks for a file name and after I provide a file name (for example: rom2) and press Enter, it asks me if I want to add the file rom2.qip to the project. No Mega core wizard opens. an empty file named rom2.qip is added to the folder.

Hope this gives enough info.

Thanks,

Assaf

Hi Assaf,

Thanks for the details.

I have also realized the same behavior for Quartus 18.1(Lite & Standard edition) with Cyclone 10 LP( 10CL025YU256I7G), but for Quartus 18.1 Pro with Cyclone 10 GX ROM : 2 port IP works fine.

It works fine for Quartus 17.1 std & 16.1 Lite with Cyclone 10 LP( 10CL025YU256I7G).

Let me check about this unexpected behavior with team & get back to you.

" In the other system, the megawizard opens up and I was able to customize/configure the ROM instance and generate it successfully without any issue."

@Abe Could you please confirm that, your design consists of Quartus 18.1(Lite & Standard edition) with Cyclone 10 LP( 10CL025YU256I7G)? and if that`s the case please provide screenshot of it.

Regards,

Vikas

Hey Vicky,

Following up on this issue.

I saw a new Quartus version (v19.1) on the website, but it is only at Pro level. Is it supposed to fix this bug? is there a schedule for a Lite release?

Thanks,

Assaf
