Sun recommends that Java v1.3 be used instead; however, Xilinx CORE Generator 3.1i runs with Java v1.2.
解决方案
When CORE Generator 3.1i was introduced, the Pentium 4 platform was not yet available for testing, so it was not possible to avoid this problem.
Xilinx is aware of this issue regarding CORE Generator 3.1i and Pentium 4 machines. CORE Generator 4.1i, which is scheduled to be released in the summer of 2001, will be compatible with Pentium 4 machines.
If it is urgent that CORE Generator be used, please contact the Xilinx hotline for information on a work-around. (1-800-255-7778). However, Xilinx generally recommends that the CORE Generator be run on non-Pentium 4 machines if possible.
