5CEBA7F27C8N JTAG Interface Debugger Support

Question

Hello,

USB Blaster UG-USB81204 is considered for Debugging Cyclone V (5CEBA7F27C8N)

1. What is the maximum TCK frequency that is supported by USB Blaster UG-USB81204
2. What will be minimum and maximum output delay on TDI and TMS lines from falling edge of TCK
3. What will be the setup and holdtime requirement of TDO line wrt to TCK rising edge of USB Blaster UG-USB81204
4. Will the debugger generate TCK signal with 50% duty cycle only?

Hello Fakrul,For USB Blaster Debugger also, the same timing specifications mentioned in Cyclone V datasheet will be applied? Please confirmwith regardsShiva

Hi,the only relation between USB-Blaster and Cyclone V timing specification mentioned in previous post is that USB-Blaster surely fulfills Cyclone V requirements. That wasn't your question as far as I understand.I tried to answer your original question in cross-posted thread https://community.intel.com/t5/FPGA-SoC-And-CPLD-Boards-And/USB-Blaster-Download-cable-Timing-Specification/m-p/1643839Still not clear to me what you want to achieve. If you have specific questions not directly related to Cyclone V debugging, you should ask explicitely.RegardsFrank
