Using JTAG HS2 with Synopsys Metaware

Question

Hi,

I use JTAG HS2 with Synopsys Metaware for ARC debugging.

I can download the information successfully. However, the speed is very slow. The download speed is about 1KB/s.

I checked the protocol with logic analyzer and found the root cause is that the gap between IR and DR is about 1ms.

One DWORD takes IR-DR-IR-DR.

Was the gap caused by HS2 HW, driver or software?

Thanks!

Hi Sky Hsu,

I'm sorry to hear that the download speed is about 1KB/s. The programing solution is provided by digilent but the download speed is determined by Synopsys. Have you contacted Synopsys customer support?  

Thank you,

Jon
