ISE 7.1 unisims and cver simulation

Apr 05, 2005 1 Replies

Hi all,



Up to now i've been using ISE 6.3 together with gplcver for simulation. Some things seem to have changed with ISE 7.1, since gplcver doesn't seem to like the simulation verilog modules of some components. For example, when simulating the DCM, cver tells me the following :


**/opt/xilinx/verilog/src/unisims/DCM.v(43) ERROR** [1044] instance/gate "MAXPERCLKIN" type "localparam" connection list expected - = read
**/opt/xilinx/verilog/src/unisims/DCM.v(44) ERROR** [1044] instance/gate "MAXPERPSCLK" type "localparam" connection list expected - = read
**/opt/xilinx/verilog/src/unisims/DCM.v(46) ERROR** [1044] instance/gate "SIM_CLKIN_CYCLE_JITTER" type "localparam" connection list expected - = read
**/opt/xilinx/verilog/src/unisims/DCM.v(47) ERROR** [1044] instance/gate "SIM_CLKIN_PERIOD_JITTER" type "localparam" connection list expected - = read
**/opt/xilinx/verilog/src/unisims/DCM.v(356) ERROR** [753] instance i_max_clkin pound parameter maximum_period (pos. 1) expression MAXPERCLKIN only parameters and constants - is parameter from other module?
**/opt/xilinx/verilog/src/unisims/DCM.v(357) ERROR** [753] instance i_max_psclk pound parameter maximum_period (pos. 1) expression MAXPERPSCLK only parameters and constants - is parameter from other module?

(sorry for the unwrapped long lines, but that's just the output)



I must admit I haven't looked into much details about what might be causing the errors, I first wanted to check if anybody else ran into this, and if there's a (simple) solution. Any hints ?



Thanks,

the errors,

(simple) solution.

Did you talk to Andrew or Steve about the problem?

Best is to create a small test case and send it to the authors.
