re: Cypress release PSoC Creator 2.0

There seem to be alot of applications that don't require 168MHz and the PSoC parts have been around long enough to make the Triscend disease unlikely. I do like the fact that the tools are integrating TOWARD the IDE and away from the FPGA place and route flows.

There are also downsides to the 'all things to all users' approach : The PSoC Creator build times are glacial - there are so many software jugglers involved. The IP components may be flexible, but sadly they too are rather slow. Their specs give 15MHz for 16 bit counters. This beta (select customers only) release of v2.0 claims 20% better routing, but that's only 18MHz... Contrast that with a STM32F4, which claims 168MHz 32 bit counters (and much more Flash/Ram/CPU/FPU for similar prices...) There also seems to be a significant silicon cost to the 'all things' approach. PSoC parts are not cheap, and may yet suffer the FPSlic/Triscend disease. It is looking faster and cheaper, to deploy two focused parts.

LATEST ARCHIVED BROADCAST
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
