1. Purpose

 To report performance comparison between  new version of VeritakSV416A and Others.


2. Test Result
Measure time between start and finish of the simulation.

2.1 Comparison between VeritakSV3232 and Certain Simulator


Designs are from www.opencores.com with minor modifications. You can download sources by google search.
VeritakSV is 2,3X speed in ac97, while VeritakSV is around 0.5X in m68K.

2.2 Comparison between VeritakSV3232 and ModelSimXE

VertitakSV　runs at 33X speed in usb benchmark.

2.3 VeritakSV 32bit -64bit Comparison



VeritakSV6464(GUI64bit/Simulator64bit) shows 10% degradation in ata.
VeritakSV6432(GUI64bit/Simulator32bit) shows 5% degradation in ethernet.



VeritakSV6464 shows almost the same performance as SV3232.

2.4 Comparion between W/O waveform histories and W/ waveform histories

With waveform addtion,40% performance degradation is shown in generic fifos benchmark on SV6464.One note is wb_dma requires 20Gbyte-30Gbytes for saving all waveform histories.


2.6 Comparion of CPUs

2500K shows around 20-60% higher performance.

3. Consideration


VeritakSV shows around 23X peformance as compared to initial veritak version.
Great advantage of VeritakSV is with waveform histories on 64bit GUI..
