Warp (Cypress)

Warp is a VHDL low cost development system for CPLD by Cypress Semiconductor Corporation. The cost is low (about $99) because of its simple architecture. Warp contains an interactive simulator (Aldec) and a compiler (Galaxy).

Unlike the IEEE 1164 standard, Warp supports only 6 logic levels: "0", "1", "Z", "L", "H" and "-"; "X" (strong drive logic unknown) and "W" (Weak drive unknown) aren't supported. The arithmetic operators can be supported by system only if the appropriate library is linked.

With Warp a project can be written only with VHDL both with behavioral and structural architecture. Aldec is the simulator that can do pre-synthesis and post-synthesis simulation. Pre-synthesis simulation is useful to verify that VHDL program works as expected and post-synthesis simulation keeps also propagation delay.

Projecting steps

• VHDL or Verilog code writing with graphic editor
• Code simulation to verify that program works as expected
• Synthesis after choosing a specific device
• Automatic fitting (mapping logic functions into PLD logic blocks)
• Post synthesis simulation with timing informations

At the end of the process ISR, a programming software, generates a "jam" file containing the bit streams needed to programming PLD macrocells.

At the current date (Dec. 2009), Cypress Semiconductor have no longer Warp for sale because license agreement with Alder Simulator expired, however, Cypress still provides technical support for previous customers
