*Obsolete* 2.1i JTAG Programmer - Data string is larger than the specified svf bit length

Description

Keywords: svf, auto, increment, bit length, program, verify, SDR

Urgency: Standard

General Description:
The SDR commands in both the "auto-incremented program" and the "auto-incremented verify" are incorrect. The SVF specifications state that "The scan data cannot specify a data string that is larger than the specified bit length."

The TDI data of "(ffff)" is larger than the specified bit length of "14".

SDR 14 TDI (ffff) SMASK (3fff) TDO (0003) MASK (0003) ;

SDR 14 TDI (ffff) SMASK (3fff) TDO (017f) MASK (3fff) ;

解决方案

Edit the file and change the TDI parameter to match the SMASK parameter as follows:

SDR 14 TDI (3fff) SMASK (3fff) TDO (017f) MASK (3fff) ;
